A Google recruiter contacted me about a week after I submitted my resume online to schedule a phone interview.

After a few days, I was contacted by one of the team members for the interview.

The conversation was polite throughout, but after a few questions on PCB production, the questioning veered off and heavily emphasized quality control and management.

The interview lasted around 30 minutes.

2. Name a chemical used in the stripping process during PCB production. Magnesium Permanganate (MgMn2O8)

3. Name the continuous quality improvement tools.
