I had two interviews where I met an HR person, the CEO, and a client. I had to wait for more than an hour as the client I was applying with was late. They made me leave and called me back 10 minutes later as the client just arrived. Some of them were pretty unprofessional during the interview. A few days after, I received a call to offer me a job with them (not with the client) telling me they would send an email with a contract for me to sign. I waited a couple of days and tried to call them back, as I had no news from them. They simply ghosted me and never returned my calls. Truly unprofessional. Would not recommend.
