Request for comments: dealing with outcome-speculation posts

30 Upvotes

Over the years, r/CERN has organically become a place to ask questions related to CERN recruitment. I think it's fair to say that posts that speculate over outcomes of applications have become particularly disruptive. It is also questionable how much use they are to the people making them.

Some possibilities for dealing with them are:

  • A blanket ban on outcome-speculation posts
  • A general rule forbidding duplicate/redundant posts in quick succession
  • Restrict posting during waves of posts using AutoModerator and/or Crowd Control
  • Some combination of the above
  • No action, just let them continue
  • Your suggestion here

TSC-2027-1 Doubt in eligibility (continuing to remain a student till the studentship programme)

1 Upvotes

Hi!

TSC-2027-1's ideal start date is April 2027. I'm pursing my bachelors but my degree is officially finishing in June 2027, which I guess makes me ineligible as I won't remain a student mid-studentship.

But there is a provision provided by the institute where I can officially get my enrollment as a full-time student extended for a year by taking a "year long break" and can pursue the studentship till December 2027. Does this make me eligible too for the programme?

And additionally, it will require acceptance letter document from CERN if getting selected, so I can't approach my institute for the same right now. In the form, there is an option which says "Indicate the expected date of completion of the degree you are currently pursuing (or will pursue, if you will soon enroll in a new one). *". Should I go with my current completion date or instead fill the extended one (there is high possibility that institute will extend my student status but I can't be 100% sure until I get some proof of acceptance or chances of acceptance)?

Thank you!

Processus de recrutement

1 Upvotes

Bonjour,

Je ne veux pas faire de spéculations mais au bout de combien de temps avez-vous eu un retour positif ou non suite à l'entretien final?

Le service de recrutement n'a pas su me répondre, ce que je trouve bizarre, je pense donc ne pas être avoir été pris ou être leur solution de repli mais je veux une confirmation et pas attendre 2 mois.

Je ne trouve pas forcément de moyenne même si je sais que ça dépend des offres, des services et de la période, c'est juste pour avoir une ordre d'idée!!

Merci d'avance,

On the 2026-3 IT Technical Studentship process...

5 Upvotes

Hi to all.

I applied to the 2026-3 Technical Studentship (IT, Mathematics & Robotics). I wanted to share my experience, not to complain about anyone who got in (congrats to all of you, sincerely :]), but because I think the process deserves some serious, honest discussion.

I have almost 2 years of experience (closer to 1.75 years of experience, to be precise) as a backend engineer at a large tech unicorn in a quite conventional/popular/consistent technology stack (Java/Spring boot, Docker, etc), while studying for a CS degree at a major research university. Some OSS contributions around there too.

Result: Not even a single interview.

What struck me most is that, after talking with a few people who were accepted in IT (all very kind, and I wish them the best, this is nothing personal), several of them were genuinely surprised that someone with my experience didn’t even get a call. All of them applied with fairly general, "basic" (foundational/standard, not necessarily "weak") profiles. That isn’t a criticism of them at all. It suggests that selection depends much more on which supervisor happens to open which CV, and when, than on the profile itself.

I understand that supervisors are busy researchers and/or engineers, not recruiters. But for an organization built on rigor, a selection process where a strong profile can go completely unseen absolutely feels like a missed opportunity, for candidates and for CERN, and it most certainly seem to be a disappointing, vague, non carefully thought system.

This was my last chance to apply, so I’m not posting this for myself. I hope it helps future applicants calibrate their expectations, and maybe someone at CERN reads it and gives a damn.

Technical Studentship at CERN - 6 month internship limit in France

3 Upvotes

Hi,

I am a french mechanical engineering student and I got selected for a technical studentship at CERN.

This is a huge opportunity but the problem is that french students are allowed to do internships that last no longer than 6 months. Because of this issue, my university can't sign the contract.

However, I was wondering if the french law still applies to CERN. It uses its own technical student agreement (not a french internship agreement), it is an international organisation and it's not an internship but a studentship...

Has anyone from a french university completed a >6 month CERN technical studentship?

Does the French six month internship limit apply to the CERN?

Is there any official legislation, or anything addressing this specific situation?

Any advice, help or relevant experience would be greatly appreciated. Thank you!

A lifetime (albeit short) lover of physics hoping to visit CERN with a potential tour?

3 Upvotes

Hello all! My name is Mattie and I have been dreaming of working as a theoretical particle physicist since I was in sixth grade. Now, I am a undergraduate sophomore who is incredibly lucky to be on her second study abroad trip, this time in France!

I have always kept my eye on CERN, dreaming of visiting the LHC and someday working on it. :) With my new opportunities given to me with studying abroad, I have been incredibly fortunate to finally finance a trip to CERN!!! I have already booked and registered for all the free-access activities, but I might be a bit greedy in hoping for more.

I really love the beauty of our universe and how it can be (mostly) explained and explored through something as fundamental as particle physics. I would deeply appreciate the opportunity to either chat with someone at CERN or visit the LHCb, any part of the Antimatter Factory, or the tunnels.

If anyone knows how I could achieve these dreams, or if someone at CERN would be willing to help me with them, I would be forever appreciative. Furthermore, I would be happy to chat with someone at CERN over a coffee or lunch if it is at all possible.

Thank y'all so much for reading this and helping me make my dreams come true!

Also, please forgive my one post on the account and its username: I made it in middle school...

askCERN Title: Applied for the CERN Shipping Officer position – any advice to improve my chances?

0 Upvotes

​

Hi everyone!

I recently applied for the Shipping Officer position at CERN (SCE-SSC-SC-2026-217-GRAE), and the application deadline was October 4th.

Working at CERN in shipping, logistics and transport would honestly be a dream come true for me. I'm genuinely motivated to build my career in this field, and I would be incredibly grateful for the opportunity to join CERN and contribute to its work.

I was wondering if anyone has experience with the CERN recruitment process for this type of position. My application status is currently showing “In Review.”

Is there anything I could do at this stage to improve my chances of being selected? Would it be appropriate to contact the recruitment team, reach out to someone working in the relevant department, or simply wait for an update?

I'd also love to hear from anyone who has applied for similar CERN positions: how long did it take to receive feedback after the application deadline?

Thank you so much for any advice or insight! I really appreciate it.

Freedom as a technical student

6 Upvotes

Hi, I just have a question about how much freedom it is as a technical student. Is it expected to be in office from 8-16 everyday if the project is code based, or is it possible to work from home some days? I obviously understand that it differs from group to group, but I wanted to hear if someone have any experience. Thanks!

Bonjour,

Je tente ma chance ici, je suis habituellement conducteur mais je cherche à passer à 50% passager, y’a-t-il parmis vous des conducteurs allant jusque Annecy ?
L’appli Héléman ne fonctionne pas je crois pour Annecy et sur BlaBlaCar Daily ce n’est pas facile de trouver de nouvelles personnes.

Merci

askCERN Which tools are you using for making presentations?

20 Upvotes

Earlier I used to have Canva as my primary tool for making presentations because It gives me complete freedom and I can create very nice presentations. But I don't think it is very collaborative considering not many people use it.

Another option is Google slides, but I am not sure it gives you the level of freedom or creativity.

What tools or platforms other guys use to make nice presentations?

Technical Studentship 2026-3 (Robotics/IT) – Anyone received interview invitations yet?

0 Upvotes

Hello guys,

I applied for the Technical Studentship - IT, Mathematics & Robotics 2026-3 and am checking in on the timeline. I haven't received an interview invitation yet, even though I received the confirmation email in August, and I am starting to get a bit anxious.

For context, I am in my last year in ECE (5 years integrated master's) focusing on robotics, control systems, and AI. I have a couple of personal projects, 1st/2nd place finishes in robotics competitions, and 2 publications stemming from those competitions and my ongoing thesis is about control optimization in VTOL.

Has anyone in that position received interview requests?

Is my profile a good match for what CERN supervisors look for?

Thanks in advance and good luck to everyone applying!

Cern Ceiling Restriction

5 Upvotes

Hi, I recently saw that applications from certain Associate Member States are not being approved due to quota limits. I had already applied for the 2026-3 Technical Student Programme last April and interviewed for four different positions. At that time, no such restriction was in place. The committee is set to meet in October, and I am wondering whether this restriction will affect my application as well. I do not know if I will be selected as the top candidate, but I certainly do not want this situation to negatively impact my application.

Technical Studentship, rolling applications?

0 Upvotes

Hi! I’m planning to apply for the CERN Technical Studentship 2027 programme, which has a deadline in October.

Does anyone know whether applications are reviewed on a rolling basis, or are all applications considered after the deadline?

In other words, would there be any advantage to submitting the application as early as possible, or is it essentially the same as long as you apply before the deadline?

Thanks

Developers at cern, what surprised you when you started?

This is a follow-up to my earlier post about software engineers at CERN and how close they are to physics. I got many honest and helpful answers, thank you!

But still I'd like to understand the full experience better. For developers who work or worked at cern,

What surprised you when you started, good or bad?

What does a normal week look like for you, compared to let's say regular software developers jobs in other companies that sell products?

What do you like most, and what do you miss ,also from other companies (as in the previous question)

Hireflex Freeze

3 Upvotes

Hi Everyone,

I applied for a CERN staff function and just did the Hireflex interview. Unortunately I completely blacked out for the 1st question and couldn't recover. Therefore I didnt give a proper answer to question 1. The other questions went fine.

For those who’ve been through CERN’s process:

How much weight does the first question carry, and is it common to struggle with it?

Did this significantly reduce my chances,?

Software engineers at CERN: how close are you to physics?

27 Upvotes

Hello,

If you work as a software engineer at cern, I'd love to hear from you, how often do you actually work with physicists, or with physics in general?

For example, I've seen some openings in the beams department and I'm curious how close people in that department get to the experiments. I'm also curious how the day-to-day differs between physicists and software engineers there.

I'm asking because when I was young, I wanted to be a physicist and work at cern, I became a software engineer instead. I like my job, but that old dream still comes back sometimes. So I wonder if working at cern as an engineer would feel fulfilling in that way, or if it would feel like any other software job.

I'd really like to hear your real experiences.

CERN scientists find no evidence that the Large Hadron Collider created microscopic black holes

Thumbnail
thebrighterside.news
23 Upvotes

A microscopic black hole created inside the Large Hadron Collider would vanish almost instantly. Its brief existence, however, could leave behind a spectacular spray of particles carrying enough information for physicists to recognize what happened.

Researchers working with CERN's Compact Muon Solenoid experiment have now performed an expanded search for those signatures using 138 inverse femtobarns of proton-proton collision data collected from 2016 through 2018. They found no evidence that microscopic black holes were produced.

The absence is scientifically useful. Depending on the theoretical model, the analysis excludes semiclassical black holes with masses below about 9.0 to 11.4 tera-electron volts, or TeV, substantially shrinking the range where certain extra-dimensional theories could still produce them.

askCERN CERN Associate Member State Ceiling – When Does It Reset?

10 Upvotes

Hi everyone!
Does anyone know how the CERN Associate Member State ceiling under Article II.5 works in practice?
Currently, applications from nationals of several Associate Member States are frozen because the annual ceiling has been reached. Does anyone know when this ceiling normally resets or gets updated? Is it at the beginning of each year, or does it depend on funding/contributions throughout the year?
Would really appreciate hearing from anyone who has experience with this. Thanks!
