First-hand accounts from people who interviewed at Mach Industries.
Software Engineer
It was a 4 round interview process. The first round was a phone interview. Then there were two technical rounds. The first technical round was supposed to be 30 mins but the interviewer wanted to extend it to an hour. The final round was 3.5 hours long. It involved preparing a presentation which took me 48 hours and then a technical interview with 3 engineers. I was ghosted for 2 weeks after the final round. I later found out my recruiter left the company. I was rejected due to internal changes in company direction. I had applied for another role but never heard back. I passed all technical rounds and my experience in defense companies was relevant. I felt it was a lot of effort for being ghosted.
- Asked typical LeetCode-style coding problems.
Electrical Engineer
I applied online via the company website. The recruiter was quick, moving me from a phone screen to an onsite interview within about a week. My second interview was with the VP of Engineering, which was a positive experience. The technical questions were reasonable and primarily focused on my resume experience. For the onsite, after my presentation, the recruiter came back right away and suddenly said the team was shifting direction. The scheduled 30-minute tour and subsequent one-on-one meetings with team members were canceled. It was very abrupt, and I was out within 30 seconds. Unfortunately, no feedback was given.
- Would you be comfortable with building weapons?
Guidance Navigation and Control Engineer
The interview process was pretty standard for startups. It started with an HR screen, then two technical calls, and finally an onsite interview. The team was really engaged and asked a lot of good questions during my presentation. The questions in the one-on-one technical calls were fair and technically well-rounded. It was a smooth experience overall, and I was impressed by the people I met.
- Can you explain how to calibrate an IMU?
- What are some methods for solving the terminal guidance problem?
- What estimation techniques could be used if the vehicle is in a cloud and GPS is unavailable?
Engineer
Applied for an analysis role even though my background is design, which I mentioned multiple times. The process had 5 phone calls that felt like repeats and were uncoordinated. Had to remind them where I was in the hiring process. Some interviewers seemed to be college students but presented as full-time staff. The on-site had two 1-on-1s, which were just repeats of earlier phone screenings, even with the same people. One interviewer smelled of alcohol. Also did a technical presentation that was interrupted by jokes and banter. Noticed a room with bunk beds. They ended up saying they wanted someone with an analysis background, despite my constant reminders about my design focus. Wasted a PTO day.
- Tell me about aircraft design.
- Solve this brain-teaser.
- What's your approach to this odd-ball question?
