I had an initial technical interview that included basic questions about my career experience, frontend technologies, and an easy-to-moderate difficulty data structure question to solve with code.

The interviewer was friendly, but their English was not the best. This made communication difficult in an interview setting and challenging to understand the requirements. They also weren't very familiar with the web-based tool we used for interviewing.

Perhaps it would have been better if the question was presented in writing, as I wonder if I missed something due to the language barrier.

However, my impression from the interview was that I had done well and a next step would be possible. Despite this, I received a generic rejection email the next day, which made for a frustrating and disappointing experience.

Data structure coding exercise (won't since I had to sign an NDA).
