  • From the unsorted integer array, find the first missing integer in sequence.
  • Given an input string, sort the characters under each word alphabetically without sorting the entire string.
  • Count number of zeros and ones in an array.

They selected the candidates based on their ranks in the coding test.  

Round 2 (Technical Interview-1 ): The interview was held on Zoom platform. It started with basic introduction and discussion on my projects. They gave me a couple of questions which were there in the coding round and asked me to explain the approach while writing the code. Then they asked a few SQL questions-

Round 3 (Demo Interview): A Salesforce based assignment was given in which 8 objectives were to be fulfilled. A week’s time was given after which I was supposed to give the presentation in front of a panel.

Questions related to that particular assignment were asked along with Salesforce concepts. They asked me to share the screen and implement a few  assignment objectives from scratch.

It was a 60 minutes round.

Round 4 (Culture Fit interview): It was a fun and easy going round so that we could know the people and the culture of the company.
