Perguntas de entrevista [1]
Pergunta 1
1. The depth of an n-ary tree. Full code
2. Finding the top K element in running stream of integers.
3. Findinf top k% of element in running stream of integers.
Next round.
1. Searching words in a Double Dimensional array consisting of characters.
-- I made using a visited array then he asked to make it without extra space.
2. Rat in a maze DP problem.
3. One more question which I dont remember.
Last round by CEO Sachin Sinha.
It was more on maths and numbers.
1. Some recursion problem on numbers then try to generate a series of a number [one path] from all possible path using some constraint so that you can always do it. Sort of generation of the private key. Real word example is of generation of credit card numbers. You can't simply increment your credit card number to get next credit card number.
2. https://www.geeksforgeeks.org/ugly-numbers/
-- I couldn't solve this. I was able to solve all other questions in every round.
Your round with CEO is the most important round.

Candidatei-me por meio de recrutador(a). O processo levou 2 semanas. Fui entrevistado pela IQLECT (Bengaluru) em set. de 2016
Entrevista
I had two Face to face rounds. There was no telephonic round before.
The interview process was precise and to the point. They have a clear idea on what skills they are looking for. As this is a startup I expected the interview to be bit more tough, but they concentrated on the basics.

Pergunta 1
- Given a limited resource, comeup with the data structures and Algorithm which can give Top-K result(with high probability) when we have continuous stream inflow.
- Implement read write lock in Linux, where read can be in multiple but write should be only one.
- Get the Nth number which is divisible by 2 or 3 or 5 where the input is a continuous whole number sequence.
- Write an algo where we have to get through minimum number of blocks in a matrix with size n cross n. Each block can be either open or close. An API generates random number to open a block. Everytime there is a open, get the least path from row 1 to row n, where if a block is set only we can move either in north/east/west/south direction.
