In the last month, I took a phone interview with Bloomberg. No behaviors questions, and there are two coding questions over there. First of all, the interviewer gave a c function prototype, and give one rule for this function, then he said I need to figure out a implementation to satisfy the rule. It's a little tricky. The second questions is finding the rule of a given number sequence, and for each input, implement a function to apply the rule to input and generate the output sequence.
