Had a call with a principle Sourcing Specialist. Talked about my current work, my programming languages choices, notice period, current salary, salary expectation. This is so far my worst experience of an interview or a phone call in general. The interviewer was late and seemed in a hurry. Normally interviewers would explain the role a bit and ask interviewees whether they have any questions about the role, but not this time. In addition, he apparently had little knowledge about the role that we were talking about, since he seemed to think that someone doing postdoc in a statistics department in university won't have a chance to able to handle the data in Deloitte. Certainly I share a big part of the fault here: I should generalise all my skills and my projects so that he can understand me. This is also my only advice to anyone who is applying for the similar role.
