There were a couple of stages of interview. 1. Online assessment 2. Phone screen 3. On-site vitual interview I've got a positive response but after they heard my salary expectation - they started to ghost me without justification of the real reason of reject.

1 - Online hackerrank test 2- Code pair 3- 3 back to back interviews *3 hours* the whole process took 1 week and a half. The whole interviewing process was very easy, I did well despite not getting an offer. I don't have an issue with this but what made it a bad experience is that they ghosted me without at least a rejection email, which IMO can indicate a bad working environment etc, if you want to interview at Tessian go ahead but make sure to have interviews with others companies in case you're ghosted
