I applied online. I interviewed at Preply in Sept 2024
Interview
I had a call with someone from HR, followed by an oral tech interview with an engineer. In the end, they provided detailed personal feedback, which was very kind of them.
I applied online. The process took 3 weeks. I interviewed at Preply in May 2023
Interview
1. Recruiter screen 2. General discussion with the developer 3. Two hours of coding interview with 2 members of the team Next stages are hiring manager interview and then cultural fit interview.
Interview questions [1]
Question 1
First General interview was more of checking what things you already know of. Second interview questions - 1. Write code for a database transaction in Django and what things could be problematic (I think this question is asked everytime as others have suggested) 2. Write a program to find the missing lowest positive integer. Eg - find the lowest +ve integer in [2,5,3,4] - should return 1 3. Question on what happens when you pass a string , a list and a dictionary to a function, and what would happen to the original calling variables 4. Design a queue for class objects and write get by index and by name functions on it And there were other general questions on backend knowledge as well
The process was really good. The challenge was interesting, more focused on the job and less on those "invert binary tree" type questions. Very focused on what they do as a company and I really apreciated that.
Thank you so much for taking the time to share how your interview experience was for the Backend Developer role. We are really excited that you've accepted our offer to join Preply. Wishing you all the best in this new exciting career chapter!
