MAQ Software Interview Experience for FTE+Internship (On-Campus)
MAQ software visited our campus in October (virtually). They conducted 4 rounds
Round 1 (Aptitude + Coding round): Aptitude Questions (30 questions for 30 minutes)
Easy to moderate level questions on quants like train speed-related, boat stream related, etc. Some questions were based on puzzles like minimum time required to cross a bridge at night with one torch this article
Note: There was negative marking for wrong answers.
Coding Questions (4 questions for 60 minutes)
Questions that I faced in my set
- Number of handshakes.
- Convert decimal number into a hexadecimal number.
- Find least D digit number with its digits’ sum equal to S.
- Simple binary tree implementation.
Some other questions which were there in my friends’ set:
- Find LCM, GCD of two numbers.
- Least number composed of 0’s and 9’s only which is divisible by N.
Note: You could submit your solution once only no resubmitting was allowed. Also all inputs for these questions were given in string form, like if inputs are numbers from 1 to 4 then they were given like “1,2,3,4” (Separated by commas). So required extra code to separate these numbers.
Round 2 (Technical 1 for 45 minutes):
- Tell something about yourself.
- Asked to write code for Spiral Matrix on collabedit.com while screen sharing was on.
- ACID properties.
- Indexing in DBMS

Round 3 (Technical 2 for 30-45 minutes):
- Tell me something about yourself.
- Why MAQ?
- Asked to write code related to finding the number of occurrence of words in a given sentence. And return an array of strings containing words in their decreasing order of occurrence. (I could not write the whole code even in 20 minutes, so the interviewer told me to just tell him approach, with which he was satisfied.)
- What data structure you will use to find total time spent by employees in the office given their check-in and check-out times, like
- So, total time spent by E1 is (10-9) + (1:30-12) ie 2hrs:30mins
- Asked about outer join and its usage example
Round 4 (HR+Technical 3 for 30 minutes):
- Tell something about yourself
- Your area of interest
