Standard software engineering interview. Data structures, algorithms, problem solving. Try to tell good engaging stories of how you solved a difficult problem using a technical solution - I think this is what they were impressed with the most.
Offer was very good, overall stable company with a lot of work in the R&D department. Highly recommended.
Interview questions [1]
Question 1

Interview
Using HackerRank.com you are being asked to write code. In the same time you are talking on the phone with interviewer. You'll see questions in left side and as you are selecting texts, writing codes, etc. your interviewer see your actions live time. Interviewer wasn't so much concerned about code to be ready to run, but more interested to see your algorithm solution.

Question 1
Merge to sorted arrays into second array, both arrays has N elements, but second array size is N * 2. So you merge both arrays in second array in a sorted way.
