EC Infosolutions interview questions

I contacted the CO-founder on LinkedIn and he assigned me a task and after completing it within two days. I submitted the assignment. And after two days the HR guy called me and given me the offer letter. After seeing the offer letter. I asked multiple questions to that HR guy, he was too impatient and he started behaving rudely to me.

It will take 1-2 days for the interview. CEO of company will directly take your 1:1 on company location. On your given answer he will judge you to take on board.
