Several in-person interviews throughout the day with personnel from various departments and lunch at a local restaurant. The interviews mostly just focused on past experiences from resume. Lunch was casual. Friendly environment.

3 out of my 4 interviews were pleasant. But my "Director Interview" was unprofessional and hurtful. The entire time, their company’s director spoke to me with an arrogant and condescending tone. He would ask rapid fire questions about technical aspects of the McMaster website and my past experiences. At times I would stumble on an answer or get stuck, and he would smirk at me as if he thought I was stupid. He asked about some of my past experiences on my resume, and after I answered, he would go out of his way to mock and minimize my contributions. He'd follow up with, "so you JUST did " and "what is the technical complexity here?" with a smirk on his face. It's hard to articulate his body language and mannerisms in writing, but I've never felt so disrespected in an interview before. Perhaps I didn't have the skill set that McMaster was looking for, but you can determine this politely without demeaning me. I took a vacation day and drove 150 miles for this interview; if I knew I'd be treated this way by their company's leadership, I would've cancelled. Please keep these thoughts in mind when you determine if you'd like to interview with McMaster. All I can say is that I’m not surprised 50% of software engineers have a negative interview experience according to Glassdoor.
