MAQ Software Interview Experience | Set 15 ( On-Campus )

Recently MAQ Software visited our campus. A panel of two members arrived.
There was a pen and paper round. The round consisted of aptitude questions like

Round 1:

• Time and work
• Pipes and Cisterns
• Calendar Dates
• Common puzzles
• Speed and Distances
  There were 30 questions to be solved in 30 mins. Each question was provided with four choices out of which one was correct. There was negative marking for wrong answers.

Next there was a round where two coding questions were given. Time allotted for this round was again 30 mins. The questions were

• Sort an array of 0s, 1s and 2s (Problem statement was not exactly the same but similar logic had to be used)
• N-queen problem for 8 queens (I gave this solution using Backtracking )

Technical 1: FTF
1) Discussion on project
