Round 4(Interview with Tech lead): This round was more like a technical discussion that tests the theoretical understanding of concepts.

Some of the questions are –

  1. What is the entire internal process that happens between entering a web URL in the browser and getting the web page loaded. Refer – what happens when we hit a url
  2. What is the maximum size of RAM that a 32-bit Operating system can run on? Ans – 4Gb RAM. 32 bit OS cannot run on higher RAMs such as 8GB. But in order to serve more requests, modern devices have RAM >4Gb. Hence, an a64-bit Operating system was introduced, which can run on RAM that is having memory till 2 TB. Read –
  3. Whenever we logged into the Gmail web app through any browser and closed the tab and when we re-open, we can get automatically logged in with our previous credentials. How exactly is that happening? Refer – Caching and cookies, How exactly browsers maintain user’s login state.

This round ended with him asking any questions/doubts regarding the role or company.

Round 5(HR Round): This round is simple. It is more like a friendly discussion with HR. 

  • The behavioral questions were asked such as Tell me about yourself and your family.
  • Why do you want to join Info Edge and whether are you willing to relocate to Noida post-pandemic?
  • Are you able to manage with Hindi (as I am south Indian)?

A strong understanding of theoretical core concepts and problem-solving abilities will help you crack the interviews.
