A multistage interview process (5 or 6 interviews including a lie detector and a test). Clear explanation of the steps. In general it was a good experience talking to the people at the company. My only issue was at the end of the process: I got an offer and instead of signing it directly, I decided to ask for a few clarifications. After my questions, firstly, the content of the offer was altered. Then the offer was withdrawn by the company without clarifications. I have consulted with employment specialists, it appeared that my questions were adequate.
