I was contacted by a recruiter to apply for the “Computer Engineering” position. I submitted application through my college’s career center. I was invited for an on-campus interview. After couple questions check my background from my resume, recruiter gave me some questions about behavior to find out whether you work well in the team environments. After that, he gave me a technical problem, which is designed a vending machine using state diagram. At this point, I kind of surprised since I didn’t expect a specific technical question at that time. I couldn’t answer the question, and blew up my chance.
