SECTION 4 - This section was domain specific. You can choose from C or C++ or JAVA. I went with 'C' and this was the toughest section for me. Know your basics. Especially pointers, array and strings(Array of Characters).
Output Questions mainly.
Lastly they will ask you to fill a form(read boring form) which is for HR purposes. Questions in the form were like:
Describe a situation when you helped some out of a tough spot when you yourself had lot of work.
Describe an incidence when you started an unpopular opinion.
Describe a situation when you worked on something you had no or little knowledge about.
Out of some 400 candidates who appeared, they shortlisted 91 and called us next day(3rd Feb) for Technical GD and HR rounds.
Day two began smoothly but turned into hooch pooch kind of situation.
GD was easy. We were allowed to discuss and choose a topic and since most of us there were together for like an hour, we had pre-decided upon a topic. But if you make it a fish market then there will be consequences. Just don't fight in the GD. Ours went very smoothly. only one person spoke at a time and everyone got appreciated.
Next was Technical interview. Questions are asked based on your domain. So they asked me about C. OS, Linked List, Networking and DBMS were asked from everyone but only basics. Following questions were asked from me:
Difference between Definition and Declaration?
What are the storage types in C? Describe them.
Difference between structure and union. What is padding in structure?
Write a function which accepts a pointer to string value as parameter and returns reversed string?
What is queue? Write a program to delete an element from a queue using arrays.
What is paging? What is page fault?
What is thrashing? What is starvation and ageing?
What are the layers of OSI model? Difference between Network and Transport layer.
What are IP addresses? What are the classes in IP addresses?
Know your basics in C and DS because they go in depth of the question.
HR round is related to the FORM that we filled earlier. It is very simple. You don't have to prepare for this one.
But They weren't sending everyone for HR round so we thought it was an elimination round but the HR Lady kept saying that Technical round was not elimination round and not everyone has to appear for HR. But I am pretty sure that no HR means no selection as in my case.
Let me know if there are any doubts.
