A call from HR. She sounded bored and unimpressed.

Then we scheduled the first interview. It lasted 2.5 hours, quite long, but the interviewer was nice and friendly.

Next, we scheduled a second interview with two more people: one manager and one developer. They were quite unpleasant, not smiling for the entire duration of the interview, which lasted another two hours. It was a bit intimidating.

They barely introduced themselves, were very quiet, and seemed highly unhappy.

If you pass, you will have another interview with a higher-up manager.

They show you a code snippet of a bank and ask what's wrong with it. These are basically synchronization questions. You will need to place some locks to protect the critical section without creating a deadlock.

Say we have a parking lot model. The code is already in production. You have objects for:

• Parking slot
• Valet
• Parking lot
• Vehicle

We would like to support different vehicle types now (like, a slot for a truck, a slot for a taxi, and so on). How will you expand the existing model? Assume the client is also a developer.

What if we add more constraints in the future, like parking slot by color or by size?
