Quess interview questions

There were 2 rounds of technical interviews. In which they mentioned that that last round would be F2F but once I got selected in the first round, they scheduled my second round of interview and kept on rescheduling/cancelling it saying that the client seems to be busy and they don't have slots.

Interview process was easy,within one day itself got the result and the hr was very helpful throughout the process.Hr gave the brief about the process and interview.Overall the hiring process was easy
