Four Tough Interview Questions You Need to Try
AUGUST 06,2019 | MANAGEMENT | By SARA KELLY
2021 will bring a soar of new candidates to your job postings so ensure you’re choosing the right candidate and try some of the toughest interview questions.
There is always a big focus on checking skills and experience in interviews, whether the focus is on personality, adaptability, problem-solving and the ability to think on your feet.
Tech companies are one industry that is using this interview method to find preferred team members that excel in these areas.
Check out four of the toughest interview questions candidates have reportedly faced at some of the world’s biggest tech companies.
Q: You’re standing on the surface of the Earth, and you walk one mile south, one mile west, and one mile north. You finish where you started, so, where are you?
A: If you are standing directly on the north pole and you walk one mile south, then one mile west, one mile north, you will arrive back at the north pole.
Q: You have 100 coins lying flat on a table; each coin has a head and a tail side.
Ten of the coins have heads facing up, and 90 of the coins have tails-up.
You can’t feel, see, or find which side is up and which side is down.
How would you split the coins into two piles, so there is the same number of heads in each pile?
A: Just count 50, and you’re done.
Q: There are three doors. Behind the doors are two goats and a car. You pick a door.
Call it door ‘A’. You want the car.
The host opens door ‘B’ which reveals a goat behind it.
You now have a choice; do you stick with Door ‘A’ or do you change to door ‘C?’ Does it matter?
A: Change to door C. When you first choose, there is a 1/3 chance of the car being behind door A and a 2/3 chance that the car isn’t behind door A.
After the host opens door B to reveal a goat, there’s still a 1/3 chance that the car is behind door A and a 2/3 chance that the car isn’t behind door A.
Surprisingly, the odds aren’t 50-50. If you switch doors, you’ll win 2/3 of the time!
Q: You have an endless supply of water, a five-litre bucket, and a three-litre bucket. How do you measure four litres of water?
A: Fill the five-litre bucket with water and then pour it into the three-litre bucket. There are now two litres in the big bucket and three litres in the little one. Empty the small bucket and pour the last two litres from the big bucket into the little bucket. The little bucket already has two litres so will only fill up by one more litre. This will leave the big bucket with four litres.
These interview questions made us squirm in our seats, and you can just imagine the candidate’s reactions let alone their responses!
Consider incorporating one in your next interview as they’re a great way to test your candidate’s ability to think on their feet, and most likely their sense of humour too!
