The tech interview process was structured yet challenging. It began with an online assessment focusing on algorithms and data structures, which tested both problem-solving skills and coding efficiency. This was followed by a technical screening where I was asked to solve coding problems live while explaining my thought process. The next round involved a system design interview, where I had to architect a scalable solution for a real-world problem. Finally, there was a behavioral interview, focusing on my experiences and how I handle teamwork and conflict. Overall, it was a thorough process that tested both technical and soft skills.

Question 1
Problem: Reverse a String
Imagine you're working with a large codebase, and you've come across a scenario where you need to reverse a string. Implement a function that takes a string as input and returns the string reversed.
For example:
- Input: "hello"
- Output: "olleh"
- Input: "LeetCode"
- Output: "edoCteeL"
Constraints:
- The input string will consist of printable ASCII characters.
- The length of the string will be between 1 and 1000 characters.
Please write a function that efficiently reverses the string and handles edge cases, such as an empty string or a string with only one character.
The entire process was pretty simple. Initially you will get an arctic shores assessment which tests your analytical and problem-solving skills. Post that, you will be scheduled for an initial screening call for 20 mins with your recruiter. You will be given a hackerrank test which includes coding+sql based on the role. If you have cleared the round,, you will be invited for a final interview with the account manager

Interview
I honestly feel like the first Java coding question in this OA is designed in a very frustrating way.
The issue is not just that the question is hard. The real problem is that the provided starter code seems to contain some very hidden trap that makes the solution fail to compile, and the platform gives almost no useful compiler feedback. You only have around 20 minutes, but you are expected to not only write the actual logic, but also somehow identify the intentionally confusing issue inside the provided code without a proper IDE or clear error message.
That makes the question feel less like a Java coding assessment and more like a blind debugging challenge. Unless you are very strong at debugging Java syntax and environment issues under pressure, it is extremely easy to get stuck forever even if your actual idea is correct.
I understand that companies want to test attention to detail, but hiding a subtle compile issue in the source code and giving no clear feedback feels unnecessarily punishing. In a real development environment, nobody debugs this way. You would normally have IDE hints, compiler logs, stack traces, or at least enough information to locate the problem.
For an entry-level or graduate-style OA, this feels especially rough because the assessment is supposed to test basic coding ability, not whether you can reverse-engineer a hidden trap in a broken template within 20 minutes.

Interview
You have an initial call with recruiter about background, schooling and experience, Then technical assessment on coding platform to test programming and Java knowledge. Then behavioral interview with questions about soft skills.
