Technical Coding System Design Behavioral
The interview process had 4 stages. First were technical questions about java, immutable, async programming, and collections. Then there was a coding part focusing on algorithms, sorting, grouping, and writing tests. After that, a system design round where I was asked about designing a link shortener service, performance, scalability, and storage. Finally, I spoke with the manager and team leader.

Coding System Design
The interview process was good and transparent, I went through 5 or 6 rounds which included coding and design interviews. The coding rounds had 2 questions that were array based and backtracking based. It was a nice experience overall because the interviewers were knowledgeable and kind. All interviews went well and I got the offer letter. However, the worst part is that they do not support with relocation, visa, health insurance, travel, or taxi and hotel expenses. You are on your own, and migrating to the UK with your family is a significant expense out of pocket. So I joined another company that offered double the salary and full relocation support. I don't understand why some organizations play games and avoid providing relocation benefits, especially UK ones, in such a competitive job market.
Confirmed questions2 questions
- Tell me about array based problems.
- Can you solve backtracking based problems?
