Dennis Group Manufacturing Engineer Interview Questions
& Process

I found the company through university recruiting at a job fair. They called me to schedule an on-site interview. I drove 3.5 hours to their Atlanta site for the interview, which lasted from about 10 am to 2 pm. I didn't get the schedule beforehand. I had around 8 one-on-one interviews throughout the day, with a 1-hour break for lunch with an employee. They said I'd get reimbursed for my drive via check in the mail, but I never got it. I turned down the offer because the salary was too low compared to average salaries in Atlanta for similar jobs. They also required 25-30% travel time with no overtime pay.

I was asked to come to the Springfield, MA headquarters for an on-site interview. I had a few smaller interviews over about 3 hours. It was pretty standard. Since the job involves a lot of travel, they asked about my willingness to travel multiple times. The engineers I spoke with asked questions about a simple process flow diagram. Specifically, they asked about fluid flow in a pipe and how pressure gauges relate to each other. These were basic fluid dynamics questions. They also inquired about any hands-on or construction experience, as they believe those candidates pay closer attention to the details in P&IDs.

I met them at a career fair and got a phone call a few weeks later for an on-site interview. It was a one-on-one with a senior engineer who really wanted to know me and if I'd be a good investment. He asked me to sell myself with experience stories. He said I'd have another interview. The second interview was a few weeks later because staff were out of town. It had four 15-minute interviews with 4 people, mostly asking about what I want to do and if I'm okay with traveling. It was less prepared than the first. I was told I was interviewing for entry-level civil engineering, but they didn't have civil positions and asked if I'd do process engineering, which I said yes to. Then, in the third round, they said they're looking for civil engineers and asked why I'm interested in process engineering. Otherwise, it was good, especially the first round.
