Got a call from recruiter after asking for a referral on Linkdein
Screening round ~ 15 min with Recruiter

1. Introduction
2. Explain one of your projects
3. Why looking for a change

Round 1 ~ 1 hour
Question 1 : https://leetcode.com/problems/first-missing-positive/
Started out by using O(n) space [using a hashmap] approach. Interviewer did not ask to optimize it so coded the solution.

Question 2 : Design a solution similar to how jackson libraries work in Java. Given a JSON, read it and implement functions like get(key) which should return a JSONobject.
Could not do it, tried doing some recursion in a class, please let me know in the comments if somebody knows how to do it. Did not get any help from the interviewer

Question 3 : Six distinct positive integers are randomly chosen between 1 and 2006 inclusive. What is the probability some pair of integers has a difference that is a multiple of 5?
We were short on time and after a few minutes the interviewer said the answer is 1 now prove it. Was able to give a proof by induction but he didn't seem satisfied, neither was I.

Rejected
