An engineering manager approached me via LinkedIn. After our initial chat, I got in touch with their recruiter, who set up a phone interview with an engineer on the team.

The phone screen was supposed to be a 30-minute discussion about my projects and some JavaScript fundamentals, followed by a 30-minute JavaScript coding test.

When I started describing my recent project, there were some follow-up questions. However, the interviewer seemed more interested in cutting me off midway than in my answers. In most cases, she said, "This much explanation is enough." I thought perhaps she was worried about the time limit.

The coding question was quite easy, and after a minor hiccup, I figured out the solution. I had also answered her theoretical questions comfortably.

Two days later, I received a rejection, and I'm still wondering why. I sent a follow-up question to the recruiter to understand my weaknesses so I can do better next time. I am still waiting...
