Ho presentato la mia candidatura tramite segnalazione di un dipendente. La procedura ha richiesto una settimana. Ho sostenuto un colloquio presso TikTok nel mese di dic 2023
Colloquio
Summary of the overall poor experience I had:
1. The interviewer hadn't bothered to book a meeting room for the interview
2. The interviewer tried to take the call from a loud communal area (think the kitchen)
3. When I mentioned the level of noise the interviewer told me to "deal with it"
4. I had to push back and tell the interviewer to move to somewhere quiet
5. The interviewer consistently interrupted my answers every couple of sentences of my response - throwing me off
6. I had to keep the interviewer on track during the interview - clarifying if I should move onto subsequent parts of the questions to keep us on time
7. Overall I got the sense that the interviewer hadn't been adequately prepped

Describe my experience through a project
Recommendation Cold Start problem
Easy LeetCode Question - median from two sorted arrays
Started with a recruiter screen with simple checks. Then went through 3 rounds of interviews. First 2 rounds were live coding with deep dive on previous projects. 2nd round went really deep of every previous work I did from MLE perspective with being questioned of every possible decision choice. Last was interview with team manager.

Recommendation system questions. Coding problems were I remember leetcode medium level.
Surprisingly straightforward — I expected a tougher challenge for a machine learning role. After a quick recruiter screen, the first technical round focused on implementing K-means clustering, which felt familiar. Handling edge cases for empty clusters was tricky, though. What really helped me prep were the algorithm explanations on PracHub, which gave me confidence going in. The final interviews were a mix of problem-solving and behavioral questions, and in the end, I received an offer that I accepted. Overall, it was a decent experience.
