Gap Data Scientist interview questions

A 30mins talk with HR starting with brief introduction. Then taking questions such as why you think you fit this position, what would be your expected salary, expected boarding date and so on. The procedure is smooth just the quality of call is sometimes poor

Received a phone call from HR for setting up interview appointment, 2 phone call from hiring manager and another data scientist who is working there. The data scientist there asked some technique questions while the hiring manager asked some behavior type of questions. Several days later I received the email from HR saying that they have move on to other candidate. No future interview process I have been through
