HR screen, then a 1.5-hour coding challenge. The HR screen just wants to see if you're interested. You should research the company, not just know that they're a car company. They provide a full autonomous solution or something.

1. Basic Calculator (+-*/). Fairly easy, finished in 15 minutes.

2. Horse sound question. Given a string (which is a horse sound), determine the minimum number of horses possible. "neigh" is the horse sound. "nneigheigh" should return 2. "neighneigh" returns 1.

Was tricky, but managed to solve it in 20 minutes.

I was contacted a day later via email saying there isn't a position open. What the frig. Why would you make me do a coding challenge, then tell me there's no position?
