Coding Behavioral Technical System Design

I saw the opening on LinkedIn and applied. After a quick chat with the team manager, he gave me a coding assignment. Then I was invited for onsite interviews. Everyone I met was really nice, smart, and professional, and the office seemed like a great place to work. I ended up interviewing with 9 people back-to-back, with 2 of them joining remotely from California. The questions were pretty direct and matched the job description. Some interviews focused on cultural fit, while others were designed to check my problem-solving and algorithm skills. Towards the end, the manager asked me to discuss an ongoing team problem and how I'd approach it. The trickiest part was a data scientist from California who asked a lot of questions that didn't seem to be related to my resume.

Behavioral Technical

I had two phone-screen interviews, which were great and on point, and I got to ask a lot of questions. Then, for the on-site, I met with 6 people one-on-one over 4.5 hours. Jacqueline met me, gave me a tour, and showed me to my room, making sure I was comfy with snacks and drinks. All the interviews started on time. They were professional and friendly, with good questions that weren't just behavioral. They even paid for my lunch! Nihal, who I spoke with on the phone, debriefed with me at the end and let me know a decision would be made within the week. It was a really positive experience overall.

Technical Behavioral

I was contacted by a recruiter who helped set up my interviews. I had applied for one position but ended up being considered for two. First, I spoke with two managers, and we determined I'd be a good fit for a specific team. Then, the hiring manager conducted a phone interview, which was pretty straightforward. After that, I flew to Seattle for interviews. They had back-to-back interviews scheduled for me. The interviewers were friendly and helpful, even though the office space seemed a bit run-down. I gathered that most people work remotely unless it's necessary to be in the office. The interview day felt rushed because I had a flight to catch, leaving me no time for additional questions.

  • Which Linux commands do you know?

Technical Coding System Design

It started with a phone screen, and if that went well, it was followed by an on-site interview. The on-site had four rounds: two were on problem-solving, the third focused on SQL for ETL tasks, and the fourth involved questions about problem-solving, multithreading, and garbage collection. They mentioned that within the first 20 minutes of the interview, they'd know if you were a good fit. If you know Hadoop, data pipelines, or real-time data processing, you should go ahead with the interview. They don't really go through your resume and focus on space and time complexity.
