I had an initial live troubleshooting interview that covered determining what was wrong. This was followed by a short programming exercise to live fix one of the issues.

That was followed up with a half-day interview with three different team members, which included a break. This interview consisted of the following:

• An architecture design problem
• Another live troubleshooting session
• A deep dive on a past project

Troubleshoot what's wrong with a live system and code a fix for it.

Walk through how you would design a system that does X, pointing out pros and cons for various options and your reasons for choosing one solution versus another.
