I applied online. The process took 2 months. I interviewed at Amazon in Dec 2021
Interview
The whole process took 2+ months.
I applied online for L4 and was contacted by the recruiter the next day. I was scheduled a phone screen interview. Upon passing that I was scheduled an Amazon loop interview consisting for 5 interviews back-to-back. After about 5 days I was notified that I passed and was upgraded to L5. A week after that I was matched with my future team and sent an offer, which I accepted.
Throughout the whole process the recruiter acted professional and kept me updated at each step. The team was very friendly. Overall, the best interview experience I'd had.
Interview questions [1]
Question 1
"Tell me about the time..." questions.
SQL easy to medium questions.
How to interpret OLS Regression output?
Explain confidence intervals.
Business acumen kind of questions.
Looking back, I'm relieved I declined the offer, despite the intense experience. The interview process felt overwhelming, starting with some tough core ML concepts before diving into the LLM fundamentals. During the technical round, I recognized a tokenization question from a PracHub session I had done just a week before. It felt like a small win in an otherwise challenging interview. Ultimately, the pressure and expectations were high, but I felt it wasn't the right fit for me.
Interview questions [2]
Question 1
LLM fundamentals: tokenization design and KL-regularized SFT
There are three rounds in total. The process begins with a coding round, followed by the main interview loop, where you will meet the team and discuss technical skills, experience, and fit.
First round is fun, second round, which is also the final round involved 5 sessions, with different focus. For some sessions, not be able to present my story completely, time was tight, and interviewers were rushing.
