I was contacted initially by a recruiter on LinkedIn, who asked if I was interested in a contract quality engineer position with Intuit. The recruiter set up a phone screen with a manager that only lasted 15-20 minutes. This screen was mostly just questions about my testing background and a few simple Java questions that anyone with Java experience should know.

I was invited on-site roughly a week later. The on-site interview was also relatively short (under an hour). I had to write a Java method, either on my laptop or a whiteboard, that involved manipulating a String. I went over this code with the team, who helped me fix a few small bugs.

They then used this code sample as an example and asked how I would approach testing the code I wrote and how I could improve it. We finished with some behavioral questions related to how I work in teams and how I'd go about talking with developers whose code I was critiquing.

Write a Java method that manipulates a string in a certain way.

If you were given this code sample to test, how would you test it?

How would you approach a developer who wrote this code to suggest changes?
