Role was for Scala development.

Two telephonic rounds were conducted, and I was rejected in the second.

1st interview covered DSA and Scala. 2nd interview covered DSA, Class Diagram, Design, and Scala.

I had a bad experience in the second round. It felt like the interviewer was inexperienced and focused too much on the Class Diagram without a clear explanation. I was not able to solve that part, but everything else went super well. Still, I got rejected.

Round 1: Project discussion.

SCALA based questions, like FlatMap, Map, fold, foldLeft.

Final and Immutable properties.

Class Diagram: Textboxes in Swing, - wanted to discuss inheritance and composition.

LRU.

Fetching top K elements in millions of unsorted elements.
