I applied online. I interviewed at SAP (Sofía, ) in Mar 2025
Interview
Technical interview was with a lot of question with a excercise at the end. Most of the question were about the OOP principles, SOLID principles and data structures. Some question about abstract classes and interfaces as well
Interview questions [1]
Question 1
Abstract class vs. Interfaces and LinkedList vs. ArraysList
Talk with HR. Went smoothly, waited a coupe of days.
Got sent an online test and I did it in time of course. I did pretty well, not perfect, but thought its more like a thing to talk about during technical interview.
Wasn't picked after so no idea on technical or later interviews
As someone who has experienced the junior software developer interview process, I can break it down into the key stages and share insights based on my experience:
1. Application and Resume Screening
The process started with submitting my resume and application. I made sure to tailor my resume to the job description, highlighting my skills in programming languages, frameworks, and projects I had worked on—particularly those involving team collaborations and real-world applications. The response came within a few days, indicating that my profile matched their requirements.
2. Online Assessment
I was then invited to complete an online coding assessment, which tested my problem-solving and algorithmic skills. The platform they used was HackerRank. The questions ranged from arrays and strings to more advanced topics like recursion and hash maps.
One of the questions required me to optimize a function to reduce its time complexity.
Another focused on implementing a basic algorithm to handle string manipulation.
I made sure to practice regularly on LeetCode and GeeksforGeeks beforehand, which really helped me manage my time effectively during the test.
3. Technical Phone Screening
After passing the assessment, I was scheduled for a technical phone screening with a developer from their team.
The interview began with a brief introduction and a few behavioral questions about my projects and technical contributions.
Then we moved on to live coding. I was asked to solve a problem involving hash maps and arrays on a shared coding platform.
The interviewer also tested my debugging skills and asked me to explain my thought process as I wrote the code.
The key takeaway for me here was the importance of communicating clearly while solving problems, as it helped the interviewer understand my approach.
4. Technical Interview/Panel Round
I advanced to the next stage, where I was interviewed by a panel of engineers. This was more in-depth and covered:
Data Structures & Algorithms: Questions about linked lists, binary search, and sorting algorithms.
System Design (Basic): I was asked to design a simple application, focusing on how I would structure the components and manage data flow.
Behavioral Questions: They wanted to understand how I handle challenges, work in a team, and learn new technologies.
5. HR Round
Finally, there was an HR interview, which felt more like a casual conversation. They asked about my career goals, my motivation for applying, and how I would fit into their company culture. This round was also an opportunity for me to ask questions about the role and the company.
Interview questions [1]
Question 1
Write a function to find the first non-repeating character in a string.
How would you implement a queue using two stacks?
Design a URL shortener like Bitly. Explain how you would store URLs, handle collisions, and scale the system.
Here’s a piece of code. It doesn’t compile/run as expected. Can you identify and fix the issue?
Can you describe a challenging project you worked on, how you approached it, and the outcome?
Explain the difference between depth-first search (DFS) and breadth-first search (BFS). When would you use each?
What are the differences between let, const, and var in JavaScript?
