Sciforn Solutions

Role: SDE - Intern

College: Not Specified

Interview Date: 16 Mar 2022

Interview Type: On-Campus

Result: Selected

Difficulty: Medium

Rounds: 2 rounds

Topics Asked: Data Structures and Algorithms, OOPS, DBMS, Computer Networks, Operating System. Specific coding problems included Array manipulation, Stack implementation, and potentially Linked List to BST conversion.

Experience:

The candidate applied for an SDE - Intern role through campus selection at Sciforn Solutions. After resume shortlisting, an online test was conducted.

Online Test: The online test was proctored and required a webcam. It comprised 28 Multiple Choice Questions (MCQs) and 2 coding questions. A sample test link was provided beforehand to familiarize candidates with the Mettl platform.

• One coding question was "Count Inversions". The problem requires finding pairs (ARR[i], ARR[j]) such that ARR[i] > ARR[j] and i < j. The candidate implemented an O(n^2) brute force approach using nested loops.
• Another coding question involved "Stack Implementation Using Array". The required operations were Push (insert if stack not full), Pop (remove and print top element, else print -1), Top (print top element, else print -1), and isEmpty (print 1 if empty, else 0).

Interview Rounds: The candidate had subsequent interview rounds. During these rounds, the candidate focused on providing optimal coding solutions and clear explanations for theoretical questions. The interviewer was supportive during the live coding session, which was conducted on a platform that was not a compiler.

Preparation: The candidate prepared continuously for three years in Data Structures and Algorithms (DSA) and dedicated two months specifically to topics like Data Structures and Algorithms, OOPS, DBMS, Computer Networks, and Operating Systems.

Tips and Suggestions from the Candidate:

• Practice questions from all relevant topics as much as possible.
• Pay close attention to projects undertaken in college or elsewhere, as they will be discussed in detail if mentioned on the resume.
• Maintain consistency in practice and explore a variety of questions rather than focusing only on one type.
• Ensure familiarity with everything listed on the resume; be precise and confident, without bragging.
• Include projects and the programming languages used in the resume.
