Pros

Lots of overtime Free snacks

Cons

Technicians are rewarded for working efficiently with additional work assignments. "Senior" technicians do the same work as entry level techs, while getting paid twice as much. Last minute travel with many adhoc extensions, sometimes keeping you away from home for multiple weeks Unfair and dishonest supervisors who will quickly throw you under the bus for a pat on the back Unsafe practices in the field Inflexible work hours and schedule This is the type of job where you are expected to be working 100% of the time, even if you complete your assigned job duties. You will be pawned off to another department for the day to ensure you don't get a break. Last time I checked, running a computer at full capacity will cause components to heat up and burn out, resulting in an unsustainable system. The same goes for humans working in a business.

Pros

The product has good potential. There are a lot of teams with a deep understanding of their product and all seems very focused to meet the company goal. As an intern you will get to a work on a project to help the team grow and scale, and it is a good opportunity to learn a lot about mechanical/electrical systems

Cons

As everybody is super busy it is difficult to have a smooth onboarding. Also, work-life balance might not be the best
