How’d You Sleep?
If you go into an office for a physical interview, make sure you look around at the other employees. If they all look tired, frazzled, and stressed, that’s a red flag. That’s a sign that the department is overworked and maybe poorly managed. Another thing to pay attention to is who is interviewing you.
If your only point of contact during the interview process is the boss of a department, that could be bad. Not being able to interact with anyone else from the department obscures a company’s true work culture. This obviously isn’t the case with all companies, but it’s just something to be aware of in case you get weird vibes.
