Reached out by recruiter.
Technical screening, 1hr, 5 python, 5 SQL

Domande di colloquio [10]
Domanda 1
Write a function to return the number of times a character appears in a string. The character can be the empty string.
Complete a function that returns a list containing mismatched words in two strings. The return list can be in any order. I used set to solve this question, but was also asked to verbally explain how I would solve it without using sets.
Given a dictionary, print the key for nth highest
value present in the dict. If there are more than
1 record present for nth highest value then sort
the key and print the first one (alphabetically). N can be higher than the number of elements in the dictionary.
Given a list of ints, balance the list so that each int appears equally in the list. Return a dictionary where the key is the int and the value is the count needed to balance the list.
[1, 1, 2] => {2: 1}
[1, 1, 1, 5, 3, 2, 2] => {5: 2, 3: 2, 2: 1}
