Interview
Applied via LinkedIn: last week of March
Got an HR call in the 1st week of April: basically asking about my experience and expectations.
1st Round:
- Intro
- Basic CS and DBMS fundamentals
- More about my open-source contributions to TypeORM
2nd Round:
- Intro
- System design: Design `Google Docs`
The interview process consisted of an initial recruiter screening followed by a technical phone interview focused on machine learning fundamentals and coding. This was followed by a multi-round onsite (virtual) interview including system design, ML theory, and practical problem-solving. Interviewers asked about past projects, model selection, and trade-offs. The process was well-structured, with each round targeting a different skill set, including research thinking, coding ability, and communication.
