A good way to assess how excited you'll be to work somewhere is by seeing how excited current employees are about their work. With that in mind, code blog Runtime Era suggests that you ask interviewers about what projects they enjoyed working on the most.
The work itself doesn't even have to be thrilling, as long as the people are:
Nobody wants to work on uninteresting things with uninteresting people. I want to know if the work is compelling and if the team finds it compelling. Even if the work doesn't sound too exciting, if the interviewer is genuinely enthusiastic about it, I'll be more interested to explore it. Passion and interest in work is always impressive.
