PayPal Interview Experience for SDE-3
There was a total of 3 rounds of interviews.
Round 1(Online Test): I got a Hacker earth test link. There were 3 questions of easy and medium. The problem in this test is we need to get input, parse it and then write the code logic. I spent more time on getting the input and parsing it rather than working on the logic alone. One of the 3 questions https://www.geeksforgeeks.org/minimum-cost-to-reach-the-top-of-the-floor-by-climbing-stairs/ I don’t remember the other 2 questions but those were easy like finding duplicates etc.
Round 2: Technical Interview
- Roll dice and generate a random number between 1-6 without using built-in functions
Round 3: Technical Interview
- Given a Input string like this ” 3 6 + 5 *” , output -> 45. Need to find this logic and implement it. Logic here is it needs to be calculated like (3 + 6 )* 5. I used stack to implement it
- Design questions
- Advantages and Disadvantages of Microservices
- Design an e-commerce site like Flipkart ( LLD)
I managed to answer all the questions and got the offer.
