I applied online. The process took 3 weeks. I interviewed at Logitech (Newark, CA) in May 2015
Interview
Applied online through Logitech's website. Recruiter contacted me two weeks after the application, onsite interview the following week. Full day and very detailed. 13 people including managers, potential peers, and people in other departments.
Candidates beware if you incur out-of-pocket travel expenses for the interview - reimbursement will take months. More than two months after submitting Logitech's arcane reimbursement paperwork for travel expenses I'm still waiting, all I've gotten to date are excuses and foot dragging (I believe Logitech's AP department is staffed by the DMV). Very unprofessional if not marginally unethical.
Interview questions [1]
Question 1
The usual experience and background questions, practical design questions, hypothetical problem resolution questions, and a few surprising college-level engineering theory questions which made me dust off memory cells from 30+ years ago.
