On Thursday, job search site Glassdoor published a list of 27 jobs with brain teasing interview questions—and not surprisingly,
many of them are in the tech industry.

These types of questions can either hurt or harm an interview, Jen Teague, a small business staffing and onboarding
coach told TechRepublic in December 2016. “When the interviewer has good grasp of the hiring procedures and what
to look for, these can be very insightful as to how a candidate thinks,” Teague said. “However, when they are added
for no purposeful reason, they will turn away good candidates. These are really good for STEM-related fields but not
usually as appropriate for other industries.”

According to Glassdoor research, the difficulty of job interviews is determined by the number of interview screens,
company size, the type of employer (public vs. private), education, and age. And, the tougher the job interview, the
more satisfied an employee will be on the job, the research found: A 10% more difficult job interview process was
associated with a 2.6% higher employee satisfaction rate later on. This is likely because a more rigorous interview
process tends to yield a better employee match for the company, Glassdoor chief economist Andrew Chamberlain
said in a press release.

Here are 27 difficult interview questions that tech job applicants might want to consider.

    Fascinating questions! In my company we ask questions about how someone handled something in the past. “Tell us about a time when…” I think these are kind of easy to answer.

    I think it is interesting that people who have hard interviews tend to be more satisfied with their position. This makes sense to me since the person would feel really good about getting said job. I recently received a promotion and the interview was difficult. I feel so good about being able to pass that interview! Not only do I like my job, but I also feel good about myself for doing well in my interview!

      That is so true Marlena. Sometime tough questions can really bring out the true character of people and leaves them with something to be proud of. I really like asking situational questions as well. Thanks for commenting!
