I recently interviewed for the SDE-1 position at Dream11. The process was thorough, consisting of three rounds in total:

Round 1: DSA (1 hour)

• The round focused on problem-solving skills and my thought process.
• Problem 1: Given an array of building heights, along with a limited number of bricks and ladders, the task was to find the maximum building (index) I could reach by using bricks and ladders optimally. My initial approach was using Dynamic Programming, but it was not optimal due to constraints. With a hint from the interviewer, I switched to a Priority Queue solution.
• Problem 2: This problem involved Binary Search, where I had to find the minimum number of days required to make a certain number of bouquets. Since I had solved a similar problem before, I was able to tackle it with ease.
• Level: Medium

Round 2: Hiring Manager (1 hour)

• This round tested both technical and behavioral skills, with questions based on my resume and tech stack.
• The interviewer used an example based on the Blinkit platform to frame the questions on REST API design and service architecture.
  1. Describe the URL structure and path variables for actions like placing an order, adding an item to the cart, and assigning a delivery partner. There were follow-up questions focused on REST API design principles, naming conventions, and service details.
  2. How would the database schema look for Blinkit? What columns would you include for various scenarios?
• Experience: The interview went well overall. Although I took some time to respond, I was able to answer most of the questions.

Result: I received a rejection two days later with feedback stating that my work experience did not align with their requirements.

I hope this experience helps others preparing for similar roles.
