Tesla Purchasing Intern interview questions

Interview was a mix of technical and situational based questions to which straight to the point answers were expected. The first round went well and I was informed about a second round a week later. The interviewer in the second round tried to grill me by obstructing my answers.

Usual 3 round interview process, first Recruiter round phone call, then manager round phone call and then another round. Overall process took one and half months to complete for summer internship.
