I applied online. The process took 2 days. I interviewed at Celestica (Toronto, ON) in Nov 2017
Interview
They will send you an email to schedule a phone interview. The phone call is practically exactly on time. As you answer the question the interviewer will be taking notes so you will hear typing noises.
Interview questions [1]
Question 1
Ask about past experience, salary expectation, the company itself( do some research before hand), so basically a background check phone interview. No technical besides if you knew this or that.
