I applied through a recruiter. The process took 4 weeks. I interviewed at Meta (London, England) in May 2025
Interview
First Round Technical Filtering: Simple LeetCode Exercise (Tree reversal) Medium Difficulty
2nd Round : - 2 LeetCode technical interviews (Harder exercises)
- 1 Machine Learning Systems interview (Create a filter for Marketplace that prevents from suggesting weapons?)
- 1 Behavioural
Interview questions [1]
Question 1
Machine Learning Systems :
Create a filter for Marketplace that prevents from suggesting weapons?
How do you get your data ?
How do you differentiate real weapons from kitchen knife ?
How do you maintain your system over time ?
Behavioural : Explain a situation where you conflicted with a collaborator? Explain your research briefly ?
The recruiter initially did not attend the interview, so it was rescheduled for another day.
After the interview, there was no feedback for over two months, and one day, the process was halted.
