Online Test (4 coding questions): 1 easy,2 medium,1 hard (I have solved 1 medium and 1 hard completely, easy 11/13 test cases and another medium 5/13)
Easy: Given a range (L, R) print all the distinct character numbers in the given range
test case: given L=10 and R=20 we have to print [10,12,13,14,15,16,17,18,19,20]
we are not printing 11 because it is having repeated characters
Medium: Given 3 points that indicate vertices of a triangle and given two more points P,Q
print 1 if P and Q both lies inside of the triangle print 2if P and Q both lies outside of the triangle print 3 if P lies inside and Q lies outside else 4

Medium: Given a string print lexicographical largest subsequence of all possible lengths
test case : "abcd" output ["d","cd","bcd","abcd"] test case 2: "dbca" output:["d","dc","dca","dbca"]
Hard:
- 31 students were shortlisted for interviews
- Interviews happened after 2 days of the online test
Interviews happened Offline Face To Face in our campus
Round1 (Technical round)(30mins):
- Why do you want to be a Software engineer (Since I am from mechanical this question was asked)
- Coding Question
- Given a String find if it is a palindrome or not
- The question was easy but the interviewer is expecting good code quality ( Take good variable names and write comments ) and handling the edges cases (such as null values and input strings having characters apart from alphabets)
- Where do you see yourself after 5 years
- Real-Time examples of Stacks and queues

14 students were eliminated in this round
Round2(Technical Round)(45min):
- Intro
- What are the different life cycle methods in react (From resume)
- A sliding window problem (a little easier side)
- Given an M*N matrix print all the Perimeter elements
test case:
12345 67890 12345 output : 123450543216
- SQL -> given a table having empid,emp_name,manager_id, print all the employees under the given manager_id
- Another SQL question is an extension of the above question, didn’t remember the question but it is a little related to hierarchy like the manager of manager (should be solved using subqueries)
- Data structures used for dfs and bfs
- Given a scenario asked me which algo you use in this case (dfs or bfs)
- Explain the implementation of the merge sort

3 students were eliminated in this round
Important:
- Different interviewers will have different way of asking questions
- For some of my friends , they were asked to design a vending machine (low level system design)(Using classes)
- For some others, questions were completely asked from resume , no coding questions at all
- So be prepared for anything
Round3 (Tech + HR )(30min)
- Tell something, which you didn’t tell to the previous two interviewers (I told about my personal Life)
- Most of the questions were from the Positions of responsibilities that I mentioned in my resume
- and they are looking for good leadership qualities
- I told about my club activities and the project that I have accomplished in the club
14 people were selected for the full-time role
Since the process happened offline, We had a great time with the interviewers and HR
Tips:
- Be prepared for offline (face-to-face) interviews
- Try to practice code on paper before hand
