MathCo Engineer Interview Questions
& Process

The interview started off with a case study that had four questions that tested problem-solving and reasoning skills. After that, we had detailed discussions about my projects, with a special focus on machine learning, to show my technical depth and how I apply it in practice.

It was a good interview process with 2 rounds. Each round had a DSA question and resume-based questions. They also asked logical thinking questions. I think they're more likely to hire someone good at Python, LLM training, chatbot development, AI, ML, etc.

I applied for the Product Engineer II - Backend job on LinkedIn. About a week later, the hiring manager contacted me, confirmed my application details, and scheduled a follow-up call for two days later. I was informed that there would be three interview rounds: two technical and one HR. The first technical round involved discussing my past work experience and then solving two coding problems – one easy and one medium. I managed to solve the easy one but struggled with the medium problem. The second technical interviewer seemed confused about the role, asking frontend-related questions despite my application being for a backend developer position. When I pointed this out, they mentioned it was a Fullstack role, which I had to correct them on, stating that wasn't the case. The hiring manager had initially told me to prepare for backend technologies and even sent an email listing the required tech stacks. I discussed the discrepancy with the hiring manager, who acknowledged the unfairness and promised to address it. However, I never heard back. Ultimately, I received a rejection email even before the interview concluded. It seems like some interviewers treat this process as a minor task rather than a significant opportunity for the candidate, which makes for a terrible experience, arguably the worst I've encountered.
