Bentley Systems Frontend Developer interview questions

Interview process was smooth. 1st round was some online test. after that 2 technical rounds including architectural questions. Last round was Director round in which he will explain the details of the company. After that they will not answer you and after 1 month if you take follow up, they will tell you that your technical rounds are clear but the position is cancelled. I mean seriously, you are wasting your as well as our time. I think the whole team is free and has no work rather doing this type of things.
