Bharti SoftBank (Hike) Interview Experience | Set 4 (Off-Campus for SDE1)

Written round :
We all were required to write a code for LRU implementation with proper Locks and synchronization so as it is thread safe.

1. Interviewer had a look at my CV for about 10 minutes and asked lot of questions of my work in current job.
2. Then a coding question that “Given a cartesian x-y plane and lot of points in that plane with x and y coordinates and 1 more point(say x,y) is given, so we have to find all the points in that plane which are lying in a radius of length r from point (x,y)”
3. Questions on Java :- Why synchronised block needed? and some more questions on Multithreading in Java.

1. Some DB queries to write for the tables provided by interviewer
2. Implement Inorder Traversal with and without using recursion.
3. How does Stack work internally and what data it holds?
