Selected Interview preparation journey
Preparation
Duration: 5 Months
Topics: Data Structures, Algorithms, OOPs, DBMS, SQL, Web Development
Tip 1 : Do not rush into things. Learning takes time. Focus should be on the concepts and not just on leaving topics half-prepared. Devote 70% of both time and effort to DSA. I solved a total of around 500 questions on sites like GFG and Leetcode.
Tip 2 : Projects play an important role too, do no ignore them. Try to get your hands dirty with a little bit of every field i.e., frontend, backend, and database.

Tip 1 : Do not lie on a resume. Everything written on your resume must be known by you in and out.
Tip 2 : Try to make a single-page resume. Highlight skills, projects, and work experience more than CGPA. Ensure proper spacing and font to maintain professionalism.

Given an array ARR of N integers and an integer S. The task is to find whether there exists a subarray(positive length) of the given array such that the sum of elements of the subarray equals to S or not. If any subarray is found, return the start and end index (0 based index) of the subarray. Otherwise, consider both the START and END indexes as -1.
Note:
If two or more such subarrays exist, return any subarray.
For Example: If the given array is [1,2,3,4] and the value of S is equal to 7. Then there are two possible subarrays having sums equal to S are [1,2,3] and [3,4].

This was a Technical + HR interview. It was in the afternoon around 12 pm. As the role was Data Engineer intern, the interviewer wanted to know whether or not I had built some projects related to this field. Most of the interview went by him asking questions based on my projects. First I was asked to explain about a project then a lot of follow-up questions were asked.
