Linkedin | Senior Software Engineer (AI/ML) | Seattle | Jan 2022 [Declined]

I had an onsite interview at Linkedin for a Senior Software Engineer (AI/ML) position. The interview process consisted of several rounds:

ML Round 1: This was an open-ended problem focused on a specific Linkedin product. I found it challenging to grasp the problem initially, which consumed a significant amount of my time. We then delved into various use-cases and strategies for data collection and preparation, concluding with a discussion on model deployment and feedback loops.

ML Round 2: This round involved both coding and discussion. One problem was a modification of a binary search problem, which I hadn't encountered on Linkedin before. There was also a problem related to large-scale random sampling, described as a modification of Random Pick with Weight, which I struggled with.

ML Round 3: This round required me to derive a modified popular ML theorem. I had difficulty understanding the problem statement, and the derivation itself took a considerable amount of time. We also discussed real-world examples and potential issues a data scientist might face, which was outside my expertise and took me a long time to fully comprehend.

ML Round 4: This was with an engineering manager. The discussion centered around my past projects, experiences, challenges faced, and how I resolved conflicts. We also tackled an open-ended problem related to the manager's team, discussing trade-offs and other relevant aspects.

Coding Round 5: This round was quite straightforward. I was asked to:

• Detect cycle in an undirected graph
• Detect cycle in a directed graph
• Solve a problem related to Permutation in String

I didn't encounter any issues in this round.

Ultimately, I received an offer, but it was for a down-leveled position as a Software Engineer instead of Senior Software Engineer. Consequently, I decided to decline the offer.
