I applied through university. The process took 2 months. I interviewed at Avaya in Dec 2012
Interview
First Contact/Interview: Got contacted by a recruiter. Basic interview questions: what makes me qualified for the job, questions about my resume, how my past experience contributes to the job.
2nd Interview: With another HR and asked similar questions as first interview
3nd Interview: A sales engineer manager and HR. In person and asked mainly about scenario questions. Also questions about resume/experience.
Final Interview: With regional manager. Felt like manager wanted to confirm with previous decisions. Questions were meant to get to know you better.
