Ex-Google recruiter advises against asking about work-life balance in a job interview.

Nolan Church, the CEO of FairComp and a former Google recruiter, advises job seekers to ask questions during interviews that demonstrate their desire to succeed and provide them with necessary information to make a decision about the job.

Both of these questions demonstrate your enthusiasm to contribute to the company's growth and offer insight into the company culture.

According to Church, the common mistake people make in interviews is asking generic, fluffy questions they found online. He recommends avoiding these questions and doing some research to prepare more effective ones.

'How does the company support work-life balance?'

The interview process is not the appropriate time to ask if the job is relevant to you.

According to Church, the question "indicates to me that you don't want to work hard." Instead of inquiring about the company's mission and demonstrating a commitment to internal achievements, you are inquiring about the length of a workday. Church considers this a warning sign.

According to Church, the question should be asked after receiving an offer. This is when you have gained leverage and demonstrated your ability to perform the job. If not, he believes you have not earned the right to ask.

'What opportunities for professional development does the company offer?'

There are a few problems with this question, Church says.

Instead of making it seem like you're a team player who wants to solve problems and move everyone forward, you come across as someone who only cares about their own advancement when you answer the question.

A broad question may not provide specific examples, which can result in a general response.

Instead of asking about professional development, inquire about the top trait of the company's top performers. This will provide insight into what you can strive for and demonstrate your commitment to success.
