While hearing this question for the first time, it might sound very simple but it could also be complex. Interviewers do not generally look for the correct answers. They would just want to see how well you are CAPABLE of analyzing a problem and what is your thought process to approach a problem.

Some TIPS to answer this question:

• Take time to analyze the answer.
• Note down your thought process while answering.
• Show that you are actually in the process of solving a problem.
• Do not blurt out answers without thinking.
• Do not say I don’t know without even trying.

Sample answer:

We know that we have 24 hours in a day. The hand first OVERLAPS at 12:00, then at 1:05, 2:10, 3.15, 4:20, 5:25, 6:30, 7:35, 8:40, 9:45 and 10:50 two times in a day. There will be no OVERLAP at 11:55 because the hour hand is moving TOWARDS 12 while the minute hand is at 11. This sums up the result to 22.
