This was one of the worst interviews I have attended.

First, there was a machine coding round. The allotted time was two days, and I completed it within one. However, there was no response to the coding test that was completed.

After multiple requests for feedback on the coding round, I was called in for a face-to-face interview three weeks later.

In the face-to-face interview, we went through the codebase I had provided, which should have been done even before calling me. I am sure the sophistication/complexity of the code did not get through to the interviewer.

Following that, there were a couple more rounds on data structures and JavaScript, in which I answered almost all questions correctly, except for a few that shouldn't have been deal-breakers. After all the rounds, I was told that the interview panel would convene for a final decision and let me know by the next day. There was no response the next day, nor in a week or two. Not even after a month of repeatedly asking for feedback. A month later, the feedback was negative.

Questions arise:

• Who would wait for one month and three weeks to complete an interview process?
• What is the point of having a machine coding round if it doesn't get reviewed?
• Why would it take such a long time to reject a candidate?

Such a disappointing interview process and negative experience.
