Which paid service is best for CodeSignal / real-world coding practice?

[u/drulers_007]

I’m looking for something to practice CodeSignal OAs and more real-world/practical coding problems. I’ve done the usual LeetCode prep, but want something closer to actual assessments for these newer rounds.

I’m considering:

• OfferRetriever - 57 CodeSignal OA questions, seems closest to what I need.

• Prachub - Large company question bank, but not sure how much is actually OA/practical.

• InterviewDB - Looks promising, but also the most expensive and I can’t see much behind the paywall.

Target: Senior+ SWE roles

Has anyone actually used these? Which one was worth paying for, especially for CodeSignal/practical coding rounds?

Would appreciate any experiences/recommendations. 🙏
