I had a phone interview with a hiring manager. I was asked to be at my computer during the interview. I was asked to write three algorithms. First one: loop through all the integers from 1 to 100 and if divisble by 3, print "fizz", if divisble by 5, print "buzz", if divisible by 3 and 5, print "fizzbuzz". Another one was to reverse a string. Third one was to check if a binary tree is symmetric.
