Summary

Interview Rounds Overview

Round 1: Recruiter Screen
Round 2: Phone Screen
Round 3: Virtual Onsite (4 rounds)

Details

I had a recruiter screen to discuss my background and fit with the team. In the second round, a phone screen, I was given data and asked to process tokens online, generate embeddings, and build a model for a classification task.

After a week, I was notified that I passed and moved on to the virtual onsite, which consisted of four rounds with eight people in total. Each round had two interviewers, one interviewing for 30 minutes while the other shadowed. The interviewers asked behavioral questions, had me write algorithms on the spot, asked machine learning fundamentals, delved into my computer vision background, and asked how to handle large-scale data, operating system issues, and concurrency.
