Flipkart | SDE-2 | Bengaluru | July 2024 | Offer
Summary
I successfully interviewed for an SDE-2 Backend role at Flipkart in July 2024 and received an offer. The interview process comprised four comprehensive rounds: a Machine Coding round, a Problem Solving and Data Structures (PSDS) round, a Low-Level Design (LLD) round, and a final Hiring Manager (HM) discussion.
Full Experience
Round 1: Machine Coding Round (2 hours)
The first 30 minutes involved a briefing of the problem statement by an SDE 3, where all candidates were added to a meeting to understand the requirements. For the next 1.5 hours, I was required to code the solution in my preferred IDE and submit a zip file via a Google Form. During this part, I had to share my screen, and the session was recorded.
Round 2: PSDS (1 hour)
In this round, I was presented with two questions that were of medium-hard difficulty.
Round 3: LLD Round (1 hour)
This round focused on Low-Level Design, where I was asked to design a specific system.
Round 4: Hiring Manager Round (1 hour)
The final round was with a senior manager. This discussion revolved around my current projects, team structure, the technologies I have experience with, and some behavioral questions.
Interview Questions (4)
You are required to build an application that lets patients connect to doctors and book appointments. The day is divided into time slots of 30 mins each, starting from 9 am to 9 pm. Doctors can login to the portal and declare their availability for the given day in terms of slots. Patients can login and book appointments/ cancel existing appointments.
For simplicity you can assume that the doctors’ availability is declared for that particular day only.
Functionalities required:
- A new doctor should be able to register, and mention his/her speciality among (Cardiologist, Dermatologist, Orthopedic, General Physician)
- A doctor should be able to declare his/her availability in each slot for the day. For example, the slots will be of 30 mins like 9am-9.30am, 9.30am-10am..

- Build a waitlist feature: If the patient wishes to book a slot for a particular doctor that is already booked, then add this patient to the waitlist. If the patient with whom the appointment is booked originally, cancels the appointment, then the first in the waitlist gets the appointment.
- A patient/doctor should be able to view his/her booked appointments for the day.
- Doctors can’t provide overlapping slots.
