• This round was a technical interview conducted physically on campus.

• The interviewer first introduced himself, he was an SDE 3(Full Stack) and had 9 years of experience in the IT field and was working with Walmart for 6 years. I was not asked to code any problem in this round, it focused more on core CSE subjects.

• I was asked to introduce myself and then the discussion started on my Resume after I had explained all my projects. We went into depth for all my projects and I was able to answer almost all the question.

• We then went to DBMS I was asked about different types of SQL queries and some examples for each. I was able to answer this very well and explained each in detail.

• Then I was asked about joins and then he gave me two simple SQL tables and asked me to perform all joins and tell him the output on the paper he provided.

• Then I was asked Computer Network related questions. He asked me what happens when you message your friend on WhatsApp. I explained him the entire OSI layer on the paper and what happens in each layer as we move on. 

• He asked some more questions on CN and as time was almost over, he could not ask me on OS (but other people were asked on virtualization, segmentation, fragmentation, cache).

• After Round 1 I immediately got call for round 2. The interviewer this time was a very senior engineer as Walmart with 18 years of experience.

• She asked me to introduce myself and I did that in great detail and explained all my project in depth. She liked how I explained my projects and did not ask much on it.

• Then she gave me a simple DSA problem(Print matrix in Spiral Order). I knew how to solve it before had but approached it from beginning an explaining her what my thought process was while making changes to the code. I showed her a dry run of my code with explanation and she liked it.

• Then I asked her about her daily responsibility and what should I look into more.

• The interview ended here.

• There were a total of 10 people who were allowed for this round and I got my turn after 2 hours from Round 2.

• Again, for this round I was asked only on my project and internship experience.

• He asked me about various situation on my project and I was able to answer all of them.

• Most of the time went into discussing how to approach a problem and finding optimal solution. He was impressed by my approach and solutions and then I asked him a little on Walmart's working and his job details. He answered all my questions and then I came out of the room.
