How To Prepare for Tough Interview Questions
One of the best ways to prepare for a tough interview is to do your research to find out what to expect. By using sites like Glassdoor, you can educate yourself about the interview process, what types of questions might be asked as well as learn more about what it’s like to work at the company. On top of doing online research, reach out to anyone you know — from personal friends, to family members, even acquaintances — who works at the company or has a similar job title. You’ll get even more insider advice on what the company is actually like under the hood or what your interviewer is really looking for.
Here are a few other things to keep in mind. (1) Always practice your answers to questions out loud with a friend or in front of the mirror — trust us, everything sounds different when you run responses in your mind. Plus, if you have planned answers in advance, it’s unlikely you’ll blank when they ask that tough or wacky question. (2) Make a mental list of questions you would like to ask during the interview, and ensure you are prepared to counter with a response when the interviewer inevitably asks if you have any questions for them. Remember this is your chance to interview the company as much as they are there to get to know you. (3) Finally, don’t forget to dress the part, get enough zzz’s and eat healthy foods to energize yourself. You’ll do great!
What Makes an Interview Tough?
According to new Glassdoor economic research, the following are factors that drive interview difficulty: Number of interview screens, company size, type of employer (public vs. private), education and age. While most of these don’t come as a surprise, we found that hospitals have the toughest job interview process with a 9.7 percent higher difficulty rating compared to the average. Non-profits followed with 9.6 percent. The report also found that gender does not have any affect on interview difficulty — it appears most employers apply the same rigor to interview processes to male and female candidates.
Why Do Tough Interviews Matter?
Our chief economist, Dr. Andrew Chamberlain, found that the tougher the job interview, the more satisfied an employee will be down the line. Specifically, according to his Glassdoor Economic Research, a 10 percent more difficult job interview process is associated with 2.6 percent higher employee satisfaction later on. Why is that? Hiring is a “matching process” that connects workers and companies, and helps to evaluate “fit.” Good matches lead to higher productivity and satisfaction, while poor matches lead to the opposite.
So remember this: By preparing for and acing that tough interview, you are more likely to love your job in the long run.
