20 Toughest Interview Questions

Tell us why we should hire you?

We’re here to not only help you find a job and a company you love – but also to help you nail that interview! We’ve therefore analysed hundreds of thousands of interview reviews left on Glassdoor to reveal the 20 toughest interview questions and challenges that have been posed by UK companies. This list is designed to help you prepare for unexpected or challenging questions as employers continue to get creative with their interview techniques.

Firstly, don’t panic: these questions and challenges rarely have right or wrong answers, rather employers are looking to understand how you think, your reactions under pressure and how you may fit into the existing team. 

Don’t be thrown by seemingly complex questions. Take your time when preparing an answer and be sure to explain your thought process.
