Ho presentato la mia candidatura online. La procedura ha richiesto 4 settimane. Ho sostenuto un colloquio presso TikTok (Seattle, WA) nel mese di feb 2024
Colloquio
The recruiter only asked a bunch of questions by email. The first round was SQL coding+business case with a senior data scientist. The second round was a Python coding interview with a machine learning engineer. The third round was with the hiring manager which I surprisingly faced a difficult DSA coding question again. The interviewer did not bother to even read the question , let alone explaining it.

Colloquio
Failed for the first round interview with no feedback reason. I guest it was because I cared about my after-work life and asked questions about working duration and routine for each week. And they did give me a pretty non-satisfiable response with high possibility of long time working and lack of rest.

If we want to trick users to add their payment method directly in our app rather than using third-party payment like Alipay or Wechat Pay, how should we design the whole system and strategy?

I had a short interview recently where the hiring manager arrived late, but once it started, they dove straight into some challenging and insightful questions about developing machine learning models. The delay was a bit frustrating, but I appreciated the depth of the conversation. They were clearly focused on understanding my technical expertise and problem-solving approach. Overall, it was a good experience, though the timing could have been smoother.
