I've got an email and asked to provide 2-3 best convenient time slots for a call, what I did. After that we scheduled a call. I had to explaing all the way down from school to the current employer - why I joined, why I left/resigned and what was my experiences and responsibilities etc no specific questions, just to get to know me better and figure out if I am a good match for the company. Asked about the expectation in terms of the salary and If I am ok with traveling much around.
