HealthPlix Frontend Interview Experience

In my recent job switch, I got interviewed at many companies, HealthPlix is one of them. The interview lasted around 1 hour. Questions that were asked are of medium level.

Question 1 on Javascript: Valid Parenthesis Checker#

Given a string containing just the characters "(", ")", "{“, "}", "[", and "]", determine if the input string is valid. An input string is valid if:

1. Open brackets must be closed by the same type of brackets.
2. Open brackets must be closed in the correct order.

Input: "()" Output: true Explanation: Brackets are well formed, so we need to return true

We have created an article and a video on this question, below are the links.
