Tails.com Technical Lead interview questions

Started with recruiter reaching out to me. A 30 minutes initial discussion with one of the software engineer who asked me about my past experience, my past projects, nothing much technical. After that I was given an assignment, which as per them was a task for 2-3 hours (There were two problem statements in the task brief, I didn't ask them whether I was supposed to solve, full-stack one or back-end one. So I solved full-stack one despite having less experience with front-end) Task was not a 3-hour assignment for sure, or I am slow. I didn't make it and I was not given a feedback, I just received 'I didn't make it' through recruiting consultant. Overall the process looked standard, and would help to assess a candidate, the reason why I am marking overall experience as negative is because they don't share feedback. If a person can spend hours doing an assignment, they can at least tell something about why it didn't pass the bar.
