The first step is the online coding assessment.

In this round, three coding questions were asked but the process was not the same as other companies. There was no compiler and no test cases. Only the problem statement and a simple text editor. The first problem is generally an easy one, the second is medium level and the third one is a hard problem. 

You are not supposed to write the exact code for the solution to the problem. Even a step-wise algorithm or pseudocode will be enough to get you through (Still a well-commented code is advisable). The main agenda is that you must be successful in conveying your ideas to the person who is evaluating your solution.  The problems were as follows-

  3. A problem related to the convex hull.

Although I was able to solve all three (third one partially {about 70%} due to time-up), you have a good chance of being shortlisted even if you complete 2 out of the three problems. And another important thing is to use comments.

The most common mistake in this round is that candidates fail to calculate and mention the correct space and time complexity of their solutions. Remember to mention this at the end of your code and also explain how you calculated this.

Round 1(Technical Interview): The interviewer was quite friendly and calm. This round is aimed at checking whether you really have some basic knowledge of DSA and basic subjects of CS. After an introduction and some general conversation, I was asked to implement two codes- 

  1. Count distinct pairs with difference k 
  2. Length of the longest substring 

Then I was asked some basic subjective questions like Keys, Joins, ACID Properties, OSI Model, scheduling algos, synchronization, thrashing, OOPs, etc. 

Round 2(Technical Interview): This round was a difficult one. The interviewer was again a cool and friendly person. I was asked just one problem. The problem was the implementation of  LRU Cache from Leetcode. (

I struggled with this. I was not able to write a perfect working code but I kept trying and was able to explain my approach to the interviewer. The best thing about HashedIn is that they don’t want you to write a perfect code. Rather, they are interested in your approach and how you plan to implement it.

Note: There could also be around 3 if the interviewer isn’t yet impressed and wants to give you another chance.

Hiring Fitment Round: This round was just a casual conversation, much more friendly than other HR Interviews. I was asked some general questions like-

  1. Why HashedIn?
  2. Why should we hire you?
  3. Your 3 strengths and 3 weaknesses.
  4. Family background.
  5. Any involvement in activities other than an academic.
  6. Preparation Strategies.

Then after two days, the result was announced and only 5 students (including me) were selected out of the 215 students who appeared for the online coding assessment.
