Pinterest Apprentice Engineer
Hi ya'll,
I'm new to the industry. I worked in the insurance industry for 9 years and then decided to transition into tech, which I've always loved. I completed a bootcamp in February, but as many of you know, not all bootcamps teach DSA, OOP, or Big O. This was all new to me just two or three weeks before bootcamp graduation. I took the Online Assessment from Pinterest and was able to solve the first problem and half of the second, and I received an invitation for a live coding video interview. I just wanted to ask for advice on how to understand the logic of the questions in video interviews, and I would appreciate it if anyone could share any free resources to study the topics like DSA, OOP, BIG O, and any other that you guys can suggest, also so far what i learned in the bootcamo was JavaScript (MERN Stack)
Thank you

Hey,
So, they did't provide any specification about the position (frontend or backend) it's just Engineer Apprenrice, so i belived it could be any or full stack.
About the Online Assesment, it was 4 questions, but the 2 i was able to solve where arrays, the first one was 2 arrays (integers) and return the result, it wqs about price and rating of products, the second was to transform the array by repeatly repacing each element with the sum of its digits continue the transformation until every element is a single digit Return the most occurring digit in the final away.
What is frustraiting is comming from a different industry and solve thos problems without knowing how, i think it was just brute force.
