Coding Technical System Design Behavioral
Started with a 50-minute Codility assessment (went through LC medium in 20 mins). Then had a 15-minute review. After that, there were 4 separate one-hour interviews covering Angular, Spring Boot, system design, and behavioral topics.
Confirmed questions2 questions
- Could you implement a table in Angular that pulls data from a mock API, and also add filtering and sorting to it?
- Can you write the Spring Boot function to gather data from that same mock API?

Coding Technical System Design Behavioral
The process starts with a Codility test focused on Spring Boot, covering topics like caching, transactions, AOP, or Streams. Next, there's a code review with a senior engineer. After that, a full 5-hour interview loop takes place, including two technical coding challenges, a system design interview, a chat with the hiring manager, and an interview with someone from security. Despite completing the entire 5-hour session and reportedly doing well, the offer was denied for unclear reasons. Later, another recruiter reached out for a second Codility test, which was aced in half the time. However, the recruiter stated the score didn't meet the minimum requirement to advance. I strongly advise against pursuing opportunities at BNSF unless you fit their specific H1B demographic. The entire process from initial contact to the in-person interview took five weeks. BNSF is a complete waste of time; explore other options.

Coding Technical
I applied and got sent a Codility assessment. I practiced with their sample question which was leetcode-style and I could use any language. Then the actual assessment had two questions that were all about Springboot implementation. It was a bit weird because the job description seemed to focus on Python/C++ and other things I'm good at, but then they hit me with Springboot, which wasn't clear as a requirement and I don't have it on my resume. I tried emailing them about possibly getting the wrong assessment or if the job description was unclear about the Java framework, but my emails kept bouncing back and I couldn't find other ways to reach the hiring team.
Confirmed questions2 questions
- Can you implement a Springboot controller that handles HTTP requests based on the provided specifications? It needs to have 7 endpoints to support individual and list views for CRUD operations.
- How would you use Spring Boot's @Transactional annotation to implement varying service behaviors across multiple services? Make sure to handle rollback for different exceptions, timeouts, and failures.
