1. Recruiter contacts you on phone followed by email with full job description. They usually call around 30 people for interview.

2. Written test (negative marking) on JS, HTML and CSS. ( Practice many online JS tests)

3. Not sure what the criteria is but they selected around 11 candidates scores ranging from 8 to 20.

4. There are two technical rounds. First round was on pure JS. Promises, lexical scoping, call and apply, async calls(event loop). Then they switched to CS algorithms - recursion (factorial), time complexity, how to improve, etc. Few basic puzzles like find the missing number in series. For second round they asked mainly problem solving - logic questions - 1. Find common numbers from 3 arrays, parenthesis balancing, etc.

Given series of numbers in array, find missing number.

Given a function print(obj) how will you print obj with few values changed without changing original obj.

Internal working of call() (JS) function. What exactly happens when call() is called with object.
