Easy going , a lot of irrelevant question. But in general average question. You need to know ore than the actual requirement. In terms of time the interview take around 1 hours. The punctuality of the interviewer is 0 the person start the interview 30 minutes after the time set

*Very* long delay between first interview and application (2 months), but overall positive experience. First interview was with hiring manager for a phone screen, and to set up on-site interview. On-site interview was the following week with the Engineers at the Advanced Ablation Solutions; 4 interviews, each one-on-one style. Most questions aimed to test basic engineering and problem principles, and give the interviewee a chance to extrapolate on key resume experience and projects.
