Hiring process requires several interviews over several days meeting lots of people. If you pass the interview process and answer all the technical questions correctly and land the job, don’t rest easy, the interview process continues AFTER your hired!
On your first day on the job you’re giving a chair, no paper, pen, phone, or work area. Instead, you roll your chair into a cubicle with a coworker who will begin testing you. Testing NOT training. You will be asked questions, solve problems, and given test assignments.
