I interviewed at Optimal Dynamics (New York, NY) in Feb 2021
Interview
I was first given a Hackerrank coding assessment, questions were moderate. Once I passed that, I got a call for a pair programming interview. Simple question but I made a simple error which I resolved in a few minutes. Interviewer was pretty happy, but a day after the interview I got a rejection. I emailed the interviewer asking for feedback and he replied saying that they had found a better suited candidate.

Interview
There was no HR involved which was a red flag for me (all the interview process and communication was done by the team). After a part that took me more than 4 hours, they ghosted me for a month before remembering me.

Interview
The interview process started with a recruiter phone screen focused on my background and interest in logistics optimization. This was followed by a take-home technical assessment involving simulation, data analysis, and linear programming using Python — to be completed in 4 hours. After submitting, I was invited to a virtual technical round where I walked through my solution and answered follow-up questions about modeling, scalability, and algorithm choices. The final stage involved a behavioral interview with the engineering manager, focusing on teamwork, problem-solving under pressure, and past project experiences.
