Expert Backend Engineer Interview Experience - London, United Kingdom

January 28, 2026
Negative ExperienceNo Offer

Process

I applied through a recruiter. The process took five weeks.

They expect candidates to spend four hours on a technical challenge building a log processor with filtering and parallelization, only to nitpick every low-level detail afterward. Add six-plus hours of interviews, and it's honestly not worth the effort. The bar is unrealistically high, the process is flawed, and if you care about your mental health, this simply isn't worth it. Frankly, it feels easier to get into a FAANG company than into Wiz.

Questions

Build a log processor. Explain a project you previously built.
