Interview Preparation Tips

Round: Test
Experience: It was an objective type test questions related to aptitude, digital, c, data structures, operating system ,computer architecture and  microprocessor. The level of difficulty was high.

Round: Technical Interview
Experience: This was purely technical with questions relating to algorithms(binary search, sorting) ,  networks(layers and different protocols,  subnetting), projects(my final  year project in manets), 
networks  project,compiler  oriented  questions related  to  C runtime  features (Use  of  heap  and 
stack to store variables in a C program ­how they work with procedures).

Round: Technical Interview
Experience: Third round was again more of  technical and  long one to. OOPs was the main focus here. 
OOPs  concepts  were  asked.  
 

Round: HR Interview
Experience:  Basic HR questions were asked. More focus on my grade sheet. They were looking 
for consistency and they were concerned with recruiting high graders. And questions like “You 
are more of a software guy..why do you want to join this post...” Since I was desperate to get a 
job, I answered "I like challenges".

Interview Preparation Tips

Round: written test
Experience: it was elitmus test conducted by the company itself on campus. As per my knowledge only those scoring 90 percentile got selected for round 2.
Tips: Attempt only those ques that are necessary for scoring 90+ in e litmus. Specially in verbal don't attempt more then required questions, though you might be tempted. The aim is not to score max bt to score 90+

Round: Technical Interview
Experience: This was a programming based round. I was asked to write algorithms for various array linked list based problems. There was cross questioning prompting to reduce complexity and to use different data structures for same problems.

Mostly it focused on subjects like c, data structures and ADA.
Tips: Be clear with basic of data structures and algorithms. Pointers, queue, stacks, array linked lists, sorting etc are the keywords.

Round: Technical Interview
Experience: This was a information security specific round since that was my major. In depth cross questioning on my thesis topics, honeypots, network intrusion etc. Security certificates, and on the go problems to provide security solution layer wise in different scenarios. Security concept of torrents was also asked in detail.
Tips: It was more of a security discussion and throwing of ideas about how things in a particular case could work or could not. Don't worry about right or wrong answer just be clear with your reasoning about the solution you are suggesting.

Round: Other Interview
Experience: I don't know what to name this round, but it focused mainly on developing test cases for an object. Say they gave me a stapler and said to develop a test plan listing down test cases for a given object to pass so that it can be confirmed that it is a stapler. Another scenario was with a lift.
Tips: This is one round where your presence of mind and inter personal skills matter. I think the way you present your thoughts was most important here.

Round: Behavioural Interview
Experience: This was was mostly about how would you react in a given professional situation
Like your assigned work could not be completed on time, or if you are doing something wrong with the work assigned.
Tips: This is all about inter personal skills and putting your best foot forward :)
