Interview Preparation Tips

Round: Test
Experience: 30 MCQ questions testing basic logical reasoning, quantitative aptitude, analytical skills.
2 coding questions --I skipped 1st that was a mistake as it was the easiest. Basic array adhoc question.
2nd-greedy algorithm based find number of platforms for a train schedule.
1 API coding on trie data structure. Functions were all there. Problem--Given a word with a letter missing...find and print possible words from the dictionary. for example--
Input- dristisofts 5
Output- drishtisofts
drisetisofts
1 debugging question-toughest of them all for me...2d-matrix find the rectangle with largest sum.
Tips: Basic Level of Questions for me. I never explicitly prepared for those. Doable.
Try both 1st and 2nd...they will be easy...C and java are only possible languages given so can't use stl.
API will be easy only lengthy...don't panic...
If you have time, you will try 4th.

Duration: 180 minutes

Round: Test
Experience: Completely networking based problem. based on TCP protocol. packets are being dropped and changed find a way to stop it. I was able to pass all test cases. (they were having some internal problems with there test cases).

Round: Technical Interview
Experience: Lovely experience. Duration -2hours. Interviewer was a chill guy. Interview started with some light moments and we discussed about my experience with the company I did my internship with. Then there was questioning about what I did in my API coding round. I was asked to explain point by point about how I understood the problem and how I solved it. Then he started grilling me on questions based on it. One by one questions were put in some way that I had to revisit everything what I learnt in my 2nd year about transmission protocol. Everything, starting with what was the hash code used to how the window size is decided and how to reduce traffic by sending cumulative ack.
Tips: Better prepare networking before coming. Everything, every exception.

Round: Technical Interview
Experience: I was asked to tell any two of my projects. And this is where I think I got an edge over others. My resume was filled with many projects and we discussed two of my most recent projects. I had learnt about Oauth protocol and RESTful APIs so we discussed about it. Then there was this problem about a company visiting for campus recruiting wanting to conduct a test on Hackerearth + what if lights went off and students want to continue where they had left --the problem was to design a databse based on these conditions and then some questions were asked on the database I had made. Finally there was an interview scheduling problem.50 students. 3 rounds(1->P1,P2 2->P2,P3 3->P4). design an algorithm to conduct the interviews taking minimum time to process all 50 students.
Tips: Prepare your projects and DBMS as well. Be confident, build approaches to tackle problems and try finding loopholes in it and then work on those. They will be focussing more on how you will tackle a general problem and not the solution.

Round: HR Interview
Experience: Introductions with family background. Psychometric test. and then I was told to ask about the company. Interviewer was very cool.

Round: Technical Interview
Experience: This round went for almost 2 hours.
It was more of a discussion. It was on the developer's coding round. The interviewer was very cool. He tested all my knowledge about networking. The discussion on the software model went on and he kept on giving me more and more exception conditions which I had to solve for the problem.

Round: Technical Interview
Experience: This round also went for another 2 hours.
The interviewer asked me to pick any 2 of my projects and explain it to him.
After I explained the projects he gave me a question on DP.
It was also more of a discussion. I wasn't able to give him the correct answer in the end.
