Probably one of the worst recruitment teams I have encountered. I was approached on LinkedIn by a recruiter. After a brief chat, I was scheduled for a Skype "pair programming" interview.

During the Skype call, the interviewer posed a question that was neither extremely hard nor trivial, requiring consideration for edge cases. I came up with a correct approach and coded it. Although I initially missed some edge cases, I debugged the code and eventually arrived at a working solution.

The interview ended on time. Afterward, I did not hear back from the recruiter. I pinged him, but he still did not respond. After several more days, I contacted another recruiter, who forwarded my email to the original recruiter. He then "gracefully" replied with a rejection. I immediately followed up, asking for feedback on what went wrong, but never heard back from him again; he simply stopped replying.

I would advise against falling for their "pair programming" interview gimmick. Their interview process is quite binary: solve the question promptly and correctly, or you're out.

Unprofessionalism is an understatement to describe these people. I will certainly avoid applying to this company in the future.

You receive, as input, a set of people. You need to output a random and uniform list of pairs of these people for giving gifts to each other. For example, the first person in the pair gives a gift to the second person in the pair.

Make sure that everyone receives a gift, and it is not allowed for a giver of a gift to receive a gift from the recipient of his gift.
