Sportskeeda Software Engineer Intern Interview Questions and Answers

The interview primarily centered around core Java concepts, including exception handling, Java streams, and collections. The coding question was related to binary search.

Initially first was HackerRank assessment then first round was of DSA. Asked 3 questions
1) Find max sum of substrings of length k
2) Find whether 2 strings are anagram or not
3) There is a Array and Find the max sum of subsequence. If you take element index at 1 in array then you are not suppose to take element index at 0 & 2 -> I solved it with Recursion then applied DP.

Cracked Round 1.

This was a machine coding round where I have to create 3 API of Cricbuzz feature.
1) Post API which will take Match Details and we have to create points table like we have in IPL
2) Get API to fetch Point table based on total Points
3) Get API to fetch last 3 matchs of a team and there results.

This was Code review round. Interviewer first asked about my project in my current company and multiple questions like hiw many team member and how many juniors u are handling. Then we move to code review and he checked extensibility of code by asking if I have to add year wise point table then How will you add then If there are many Tournament then how you will implement.

Q1. Difference between string and string builder.
Ans. 
String is immutable, while StringBuilder is mutable and more efficient for concatenating strings.
• String is immutable, meaning once created, its value cannot be changed. StringBuilder is mutable, allowing for modifications without creating new objects.

• String concatenation creates a new string object each time, while StringBuilder modifies the existing object directly.

• StringBuilder is more efficient for concatenating mul...read more

Q2. What is async and await
Ans. 
Async and await are keywords in JavaScript used to work with asynchronous code.
• Async is used to define a function as asynchronous, allowing it to run in the background without blocking the main thread.

• Await is used to pause the execution of an async function until a Promise is settled, and then resumes the function with the resolved value.

• Async/await is a more readable and cleaner way to write asynchronous code compare...read more
