I applied through a recruiter. The process took 2 weeks. I interviewed at Pinterest in Mar 2024
Interview
Reached out by HR and scheduled first round interview. After first round interview I got ghosted. Might because I don't have much ads related DL experiences and it's a tight market so I guess I will move on.
Interview questions [1]
Question 1
Asked several easy machine learning questions for sanity check. And also deep dived resume projects. Coding question is, given a list of integer, you can add and multiply from left to right regardless of priority and ask if target could be computed. Follow up is to consider minus and divide also.
The phone screen was a mix of behavioral questions and some basic technical concepts, which was a bit different from what I anticipated. After that, I faced a technical round that focused on implementing sparse matrix operations. To my surprise, the coding question was nearly identical to what I'd practiced in the algorithm section on PracHub just days before. The onsite interview included some more DSA challenges and a discussion on machine learning concepts, which helped me feel well-prepared. Overall, the experience was smooth, and I accepted the offer afterward.

Question 1
Implement sparse matrix storage, addition, and multiplication
The assessment time was very short and harsh. There were lots of questions with a very limited time. I liked the other big companies' assessments better. For example, Meta and Google assessments are through talking to a person while coding.
I applied for the new grad MLE position. The process included an online assessment, a 20-minute HR call, and four onsite interviews (two coding and two machine learning system design).
