Is this your first time applying for a job at a Tech company like Apple? It can be quite daunting for first timers and often they are left confused with the questions being asked. But all these questions have a main purpose. Job candidates need to understand that there are reasons behind them and they can only be answered in a particular way.

Thankfully, Dino Grigorakakis, the VP of recruiting at Randstad Technologies, along with the help of John Reed, senior director for Robert Half Technologies, has come up with some challenging interview questions that can prepare you in the professional world of tech.

Here are their insights to the toughest questions that can be intimidating for anyone:

1. You have 100 coins laying flat on a table. Ten of the coins are heads up, the other 90 tails up. You do not have the ability to see or feel which side is up. How are you able to split the coins into 2 piles with the same number of heads in each pile?

The focus of this question is to see if you have good listening skills. Every coin has a head side. Just count 50 coins and you're done.

2. You put a glass of water on a record turntable and it slowly increases in speed. What happens first - does the glass fall off or does the water splash out?

This question is usually asked from engineer candidates in relation to their problem solving skills. However there are several possible solutions based on a number of factors, so employers want you to walk them through to your solution. Answering this question involves your thought process. When an interview asks a question that has multiple solutions, employers aren't looking for the "right" answer, they are looking to see whether you come up with multiple possible solutions and understand the factors that would impact the issue.

3. What is more important: Fixing the customer's problem or creating a good customer experience?

This question can be challenging. Not one job seeker would deny the importance of both but employers would want to know how you answer the question and try to understand you better by which you choose. So be decisive. Stress the importance of each. But since you're asked to choose one out of the two, then rationalize it based on your experiences. This will give a potential employer insight into how your mind works to tackle issues.
