They totally wasted my time. The process took almost two months, including a week-long software test and several hours of interviews. The software developers reviewed my test and liked my coding style.

I went to the office twice: once for a code review and once for interviews with employees and the boss.

For my last interview, which was planned with the boss, he didn't even show up. They didn't give me a reason for his no-show until I called and asked days later. One week after that, they stated they couldn't hire anyone at that moment and would get back to me in two months.

I got another job before two months had passed, but they never even called me. They also never apologized when the boss failed to appear for the interview, leaving me waiting at the office.

Almost everything that can be acceptable.

Many, many questions.
