There are several patients with some boolean type attributes. how to present them in a data structure or in a table? follow up: there are nearly 1000 attributes, most of every patient's attributes value are false, only 4 to 5 are true, how to reduce the table space?
Leetcode questions, data structures (trees, graphs, arrays, strings), algorithms. Personality questions based on principles.
There were many questions like"tell us about a hard problem you had to solve" and "did you ever do anything risky" and "did your boss ever ask you to do something that you didn't agree with"
1 algorithm problems about string, and 1 follow up.

How can you copy files from one directory to another using Python?
Implement a stack that supports push, pop and mode(the one from statistics) operation. Gave an O(log n ) push and pop and O(1) mode operation.Another good question was implement atoi function. I assumed it as base 10 but was asked to support from binary to any base numbers(even base 50).
second question. No idea how to implement in O(1) time.
Most questions are around data structures. Also expect word puzzles, like write an algorithm to spell out actual numbers. E.g. 121 -> "One Hundred and Twenty One".
