First they are asking about presenting yourself then they gave me a question of code then they asked about compilation about jit boxing unboxing classical theme of C and Java.

In initial interview asked about data types and some basic knowledge of programming, and my cv. no Leetcode yet. The interviewer was nice, and pretty knowledgeable about technology. Btw, avoid interviewing at multiple location! If you screwed up in any of them, you will be rejected automatically
