I arrived at the offices and met with the team leader. He asked a single question about a project I've done recently and then moved on to the questions. There were two coding questions for which I needed to write pseudocode on paper or a whiteboard.

The first question was to receive a string that may contain numbers, minus/plus signs, and other characters. The task was to return an integer based on specific rules:

• The first character that isn't a digit ends the number.
• The only legal character before numbers is either a minus or a plus sign.

The second question was to receive a number and perform prime factorization on it.
