Standard first call with recruiter to assess alignment between the candidate and the org.

Next round is a coding exercise over video conference. The interviewer was reasonably collaborative but kept leaning over his screen to talk to other people while we were exchanging ideas, which was a bit distracting.

I put in place a solution that worked for very simple inputs, but for more complicated ones it definitely needed more work.

In the spirit of collaboration, I asked the interviewer how he would approach it. This caught him off-guard and he was visibly surprised by the question.

After a few seconds went by, his answer was: "I don't know... I think there could be many ways to approach this."

Given a string that represents a valid math expression, implement a function to evaluate it and return the result.

e.g. "one plus two times five".
