First-hand accounts from people who interviewed at Headlands Technologies.
Software Engineer
Got contacted by a recruiter from a third party. Then I received an online assessment (OA) on Hackerrank. The coding challenge was about LeetCode Medium-Hard difficulty. The main challenge wasn't the algorithm itself, which was pretty standard, but the strict time limit and the need to handle I/O parsing and validation. In a real job, this part is minor, but here it took up way too much time to implement. I spent too much effort on I/O instead of the algorithm and couldn't finish it within the time limit. It seems like these companies really value speed and look for competitive programmers rather than actual software engineers.
- Expect coding problems similar to LeetCode Medium difficulty, with the added challenge of handling input/output.
Software Engineer
The overall process felt fair. The first round was pretty tough. It started with a HackerRank challenge that was medium to hard, more tough due to the time limit than the actual question, but I passed. Then I had a one-on-one with a developer. The interviewer was nice and seemed engaged, really representing the company well. The questions weren't basic definitions, but more about data structures (STL specifically) and very open-ended problems like why code might be slow or how to approach debugging with different tools. I didn't move on after the second round because I wasn't as prepared as I should have been. I asked for feedback on how to improve but never heard back.
- HackerRank questions - Medium to hard difficulty with a time crunch.
- STL-related questions.
- Comfortable with data-structures.
Software Engineer
Had a couple of rounds. First one was a graph problem with some C++ questions, asked why I wanted to work at this company and specifically in trading. Second round, it was mostly about introducing myself, why the company, some behavioral questions and a brainteaser. No coding in the second round, and I didn't make it past that.
- graph problem
- self introduction, why company, BQ, brainteaser, no coding, failed
