This article is an account of my experience of attending the informatica Infathon 4.0 exam. I got to know about this exam from my college and thought to give it a try. This exam had two parts the coding round and the behavioural round.
The Coding Round:
The whole round consisted to 3 question:
In the first question i was given a list of sting each of size m, the size of the list was m. The task was to construct all the unique strings such that the k th element of each string belongs to the kth string. The first question was fairly simple and i solved it using two for loops and a set.
The second question was to find the minimum cost to travel from source to destination from the given nodes and their costs. First i had to construct a directed graph for the given values. Then on that graph i performed shorted path algorithm to find the minimum cost to travel from the given source to destination. The this question is well known i took my time with it as it is lengthy to write.
The third question was to invert the given binary tree. I was not able to solve this in the given time.One unique thing about this round was that they asked the candidate for a detailed explanation of their approach in a 5 min video.
The Behavioural Round:
This round was to test whether the candidates were a good fit for the organization. Mostly all the questions were scenario related , and based on out answer we would be judged if we belong in the organization.
Verdict:
The whole experience was kind of new as i did not expect the video explanation. The level of questions was decent was can be solved with a little practice. I would recommend everyone to take part in the next iteration of this even.
