Apple job question: "62-63=1", move just one digit, make the calculation true

Apple is one of the most prestigious companies in the world, so getting a job there is no easy feat. Typically, Apple will ask a combination of technical questions (based on the candidate’s past experience) and some brain teasers to test their reflexes.

If you interview to work at an Apple retail store, you'll be asked a lot of questions about how to handle an unhappy customer.

Business Insider has compiled a series of recruitment questions that candidates who have interviewed at Apple shared on Glassdoor. These are considered the "hardest" questions that the corporation uses to evaluate candidates.

To become an Apple employee, you must go through a "brain-teasing" interview round.

Among them, there is a question that many people are interested in:

"62 – 63 = 1; move just one digit to make this equation true" –

Question for Software Development Engineer candidates. And the answer is convert the number 62 to 26 (2 to the power of 6 = 64), subtract 63 to get the result of 1.

Here are some other questions that are part of Apple's "challenge":
