Round difficulty - Medium

For me assesment was on 4.30 in the evening. the round was about 120 minute long. It had 3 coding question easy,medium and high level. And it contained some aptitude question on profit and loss, SI,CI etc. which will be easy to solve. It also contained logical question like seating arrangement, directions. And vocabulary round was also there. To solve a coding round you need to have a basic understanding. For me the easy question was to find out the prime number in array and medium level question was on profit maximization and another one was jumping cloud problem. There will be 6 coding question in which we need to solve 3.(one from easy, medium and hard).

   1. We loop through all numbers from 2 to num - 1.
   2. For every number in the loop, we check if it divides num.
   3. If we find any number that divides num, we can say num is not prime.
   4. If num is prime, we store it in the result...read more
