Total 65 were shortlisted after this round.
There were two questions in this round and the time allotted to solve both questions is 1 Hr.
First question was like printing the list as per conditions mentioned. The questions was easy but the trap over here is reading input as size of list is not given.
Second question: N*N grid is given and chef positions mark with some stepping X values( by stepping values means, he can move x steps in a day).Here we need to find a cell where all chefs can reach in total minimum days as per travel rules:
Only one chef can travel on a given day and he can travel in all four directions and chef i can take any number of steps between 1 to step[i]
Note:Chef position is marked by non-negative integer value.
Input : 4 -1 -1 -1 1 -1 -1 -1 -1 2 -1 -1 -1 1 2 -1 -1 Output : 2 0 Explanation: Chef at (0,3) can reach at target in 5 days,chef at (3,0) and chef(3,1) can both reach in 1-1 days.

Tips:Be honest,confident and make sure whatever you are mentioning in your CV is known to you starting from your projects to your skills.
Before going for an interview explore the company once,read wikipedia and relevant informations. Being an ECE student, I would advice to all ece students that you should be good in programming and have strong command over Data structures, C/C++, DBMS(optional).If you are good enough in Core please do mention otherwise simply deny.
