>Most interview questions are taken from sites like Leetcode For phone screens: sure. Frankly, a lot of people will bomb a fizzbuzz-level question at the phone screen so why bother spending time thinking of a good question that they might leak onto the internet, forcing you to take the time to make up another? Interviewers tend to take the on-site a bit more seriously and will at least add an unusual wrinkle to a leetcode question to stump anyone who just has a great memory but very little actual ability.
