Salesforce Interview Experience for SDE Internship (On-Campus)

Little Background: I am a Pre-final year student from NIT and Salesforce visited my campus in pool hiring.

Online Assessment (90 mins – 3 coding questions )

• 1 Hard DP question
• 2 medium level questions

The questions were long and they had a lot of stories and it took time to read and understand the question. I solved 2 questions with all test cases passed and the third question with 2 test cases passed.

Online Interviews (3 Rounds)

• 2 Technical – 45 mins
• 1 Hiring Manager Round – 30 mins

Technical Round – 1st: The interviewer shared a Hackerrank Codepair link.

• The First question was – Two Sum( https://leetcode.com/problems/two-sum/). This is a very easy question and I wrote the code and explained him simultaneously.
• Second Question – This was also an easy question where an array was given and I had to find out the first occurrences of the elements (something similar). I gave him a brute force approach and then later optimized it using the unordered map. He was quite happy and it passed all the test cases.

OOPS, Questions (15 mins):

• He asked me to explain encapsulation and abstraction with real-life examples.
• Benefits of OOPS,
• How do the map work and internal implementation of the map as I had used it in my coding question
• I was also asked if I have used abstract class in my project but I didn’t use it.

Technical Round – 2nd:

• First Question – Balanced Parenthesis(https://leetcode.com/problems/valid-parentheses/) ( the question had only one type of bracket)
  

input - (())(
output - false

I explained my solution and wrote the code.

• Second Question – This was a debugging problem and required the approach of multilevel inheritance. I got confused for a bit but the interviewer gave me a hint and then i answered her questions correctly.
• Third Question – Given an array check if all the occurrences in the array are unique or not. 
  Eg – 1 has a frequency of 1, 2 has a frequency of 2 and 3 has a frequency of 3. So return true
  

input - [1,2,2,3,3,3]
output - true
input - [1,1,2,2,3,3,3,3]
output- false

I gave her multiple approaches involving unordered maps, set ..and I wrote code for 2 solutions. Overall she was satisfied and asked me about the time and space complexities of each solution.

Hiring Manager Round – 30 mins: Questions I was asked were:

• Introduce Yourself
• Give a brief about your projects
• Why Salesforce?
• How were your previous two interviews?
• Can you tell me a moment when you think you did something very innovative
• I can see a lot of cp achievements on your resume..can you tell me about your cp journey
• What are the values that you follow in your life?
• How was lockdown for you..are you enjoying offline college
• What do you want to become in the future?
• What are your strengths and weakness?

I have been selected for 2 months (May-July 2023) internship and the result was announced on the same day.

Overall Review: Salesforce doesn’t focus on CP candidates and the questions asked in the interview are mostly easy. They focus a lot on their values so prepare for it well. A few of my friends were asked LLD as well. Moreover don’t get disheartened in this internship and placement season just keep preparing !!
