Scholarly Science is a start-up company which is developing technologies for the students looking for internships.
I was contacted by one of the developers who was looking for interns to join their team.
The interview consists of a single telephonic round which was mainly focused on DSA and Java. The questions on DSA ranges from strings to trees with medium level of difficulty. The focus was mainly on the approach and the same was asked to code, in extreme cases. In Java, mostly the question varies across different topics. One thing to note, the questions were mostly of oral nature where direct concepts were asked.
Some of the questions asked were as follows.
- Implement queue using a stack.
- Implement stack using a queue.

- What is a priority queue and its applications?
