Jobs interviews are always hard, but some come with trickier questions than others. Where do you see yourself in five years? How many ping pong balls fit in a school bus?

Glassdoor, the jobs- and career-focused site, compiled 27 of the toughest interview questions job seekers face in any field. The information came from job seekers and Glassdoor users who shared their interview experiences on the site. The website looked through questions that users marked as difficult to find the toughest ones across industries.

Along with individual questions, Glassdoor found that hospitals have the most challenging interview process, followed by nonprofits. The number of screenings, company size, public or private status of employer and job seekers' education and age all affected how difficult interviews were.

But it's not all bad news. Tougher job interviews correlated with better employee satisfaction after candidates actually get the job, Glassdoor found.

"By preparing for and acing that tough interview, you are more likely to love your job in the long run," Glassdoor wrote in a blog post.
