First, there was a Skype interview with questions about your previous work and some about testing. For example, you might be asked how you would test a pencil.

After that, they invite you for an interview and pay for your trip.

There are usually 3-4 interviews. You can receive an offer after the third or fourth interview, or you can be rejected after either.

The fourth interview is only conducted if they feel one more conversation is needed to make a decision. Interviews typically last 45 minutes with a 10-minute break in between.

Questions vary depending on the interviewer, but almost all of them will ask how you would test something. Algorithmic questions cover basic algorithms. You can use any programming language, but those with an object-oriented paradigm are recommended. The exact names of methods and parameters are not critically important.

I was expecting hard questions, but the questions were simple, basic algorithm and data structures.
