Data Engineer Interview Questions

Using a dictionary where the value is a counter that is increased every time a letter appears, or that adds a new key if a new letter appears. Then sort the keyset and make a new string where, for each letter in the sorted keyset, you add to a new string the letter as many times as the counter says. I picked this solution because it could be applied to sentences that not only contain a's and b's but to any type of sentence.

Hi there, Thank you for your review. I'd like to clarify a few misconceptions and provide more light of the situation. First, the interview question given to you was actually based on a real world problem we solve. Our servers index thousands of web pages per second, and we have to extract the top keywords with utmost time efficiency. Any lack of efficiency in the algorithm could cost us thousands of dollars per month in server costs. Without this mentality, we may not have grown to 130 employees in 5 years with barely any funding I'm sorry you did not progress beyond the basic questions to the more advanced ones. I admit we are definitely not the average tech company you may interview with, and I admit we are extremely selective. However, I'm extremely proud of our small team of 25 engineers, who are directly responsible in our ability to compete with competitors who have engineering teams magnitudes larger than us. I hope you'll improve your algorithms problem solving, as they are standard to all top tier tech companies based in Canada & US, and I wish you the best of luck in your search.
