It was the worst interview experience I have had with any company I ever interviewed for.

My first conversation was with an HR representative who was very rude. She bluntly said unless I told her what I was making and expecting, she wouldn't go ahead with passing my resume to the hiring manager. I decided to ignore her, hoping it would just be a temporary phase.

She immediately sent me a coding challenge, which I completed and sent the next day. The way to make sure your code gets selected is to document it very well and add unit tests to cover all possible cases. Also, make sure you send it within 24 hours.

After 10 days, they got back saying I passed the coding test and wanted to set up a phone interview. The hiring manager literally asked me to solve a problem for their project. It was a 1-hour session with me just thinking out loud to solve the problem.

The same night, I received an email saying that given the number of candidates they have, it would take 2 weeks to come back. Two weeks later, when I checked with them, saying I might receive another offer, the HR said, given the number of candidates they have, they will not go ahead with my candidacy.

And for some mysterious reason, I received another email a week later saying they would like to interview me again. I had a second phone interview, which was pretty easy, and they "confirmed" the rejection the next day through an automated email.

Super unprofessional hiring experience, and I am glad I did not end up in that environment. I don't see myself applying to this company again. It was a sheer waste of time applying to their opening.
