I was contacted via LinkedIn by the CEO, later had an interview with Boopin & their client, where I was supposed to be placed. Interviewing process got continuously rescheduled and delayed, communication from the hiring manager not clear. At the end they gave me an offer lower than my current package and declined my attempts to negotiate, saying I should have negotiated at earlier stages. At the end just stopped replying to my emails. I knew I wasn't getting the offer I wanted but they didn't even bother to respond.
