Interview Preparation Tips

Round: WRITTEN
Experience: It is a written round .

We are given with 2 coding questions of 10 marks each .There is no negative marking for coding questions

1)Given a string you have to partition the string in such a manner that each part of the partitioned string is a palindrome in itself and you have to count the number of such partition

For eg: given string NITIN
N ITI N
N I T I N
NITIN
So output will be 3.

2)You are given with a large paragraph and N words.
You have to find a min length subparagraph of the paragraph which contain all those N words in any order. Here length of a paragraph is the count of words in the paragraph.

There are 20 MCQ's all are technical questions only majorly from DSA
Tips: Coding it comes from practice . And for aptitude be good at fundamentals like time complexities etc .

Round: Technical Interview
Experience: Some times luck in interview is also important .I was unable to solve the second question initially ,but later with the help of my interviewer I was able to solve it .
Tips: Even if you are not able to solve the question initially don't be panic it will definitely go well

But as I am from Electronics I told them that I don't know all those subjects
Tips: Be good at other Cs subjects also

Round: Technical Interview
Experience: I solved above question Using DFS .I constructed a Graph using given information . and I did DFS starting from Given process .In the graph I took each process as 1 Node and the corresponding parent child relationship between the process as edges .
Tips: They will give sufficient time for thinking of the solution . So don't worry immediately after seeing the question . First think well you will definitely get it
