Worst and unprofessional interview process.

I applied on the company website. A month later, a recruiter sent an email to set up a phone call. While I answered some basic questions, she was typing without interacting with the candidate.

I told her in an email that I had time for Wednesday and Thursday for a technical interview, but another Pinterest recruiter sent me two emails: the first asked me to do it on Friday, and the second for Tuesday. What? Did they really read my email?

Somehow, I accepted Tuesday at 4 PM (1 hour).

On the coding phone interview, the interviewer seemed tired and sleepy; I heard him yawning all the time. The question was easy. I asked to clarify the question, and he did not answer properly, so I gave a solution and changed it according to his requirement. After he said the solution was good, I still had 15 minutes to ask a couple of questions about the company.

Two days later, I did not receive any follow-up, so I sent an email to the second recruiter, and she just forwarded it to the first recruiter without any answer. Then I received an auto-email saying they would not move forward with my application.

Provide a list of pins with their ID and height. Place them into k columns. Each time, choose the column with the minimum total height. Return each column with its list of pins.
