InterviewBit/Scaler Interview Experience for SDE Intern (Off-Campus)

Online Test: It had 4 questions. I solved 3/4 so I received a call for 1st round of interview. 

Round 1: The interviewer was great and helpful. she asked 2 questions and gave 1 hour to solve them.

1. Given a matrix of integers A of size N x M consisting of 0, 1, or 2.

   Each cell can have three values:

   The value 0 represents an empty cell.

   The value 1 representing a fresh orange.

   The value 2 representing a rotten orange.

   Every minute, any fresh orange that is adjacent (Left, Right, Top, or Bottom) to a rotten orange becomes rotten. Return the minimum number of minutes that must elapse until no cell has a fresh orange. If this is impossible, return -1 instead.

   A = [ [2, 1, 2]
         [1, 1, 0]
         [0, 2, 1] ]
   Ans = 1 

2. Given a non-negative number represented as an array of digits, add 1 to the number ( increment the number represented by the digits ).

   The digits are stored such that the most significant digit is at the head of the list.

   ex- [1, 2, 3]
   Ans= [1, 2, 4]

I solved both the problems so I was called for 2nd round.

Round 2: It was a development round. 

• I received a task to build a SPA where the admin can schedule interviews. I was given one day to build and had to share the Github link with them. I completed the basic requirements and one bonus point.
• The interviewer asked me the implementation details of the project (the database schema, API calls, etc.).
• He asked me to implement a new feature live on the call. I implemented that feature.
• I received the call for the HR round.

Round 3: It was just 15 min round. The interviewer asked me about my old internships and few HR questions. 

Overall I had a great experience. All the interviewers were really helpful.  

I received the call from HR  that I am selected.
