Round 1 (1 hour): Technical interview with a team member from the contracting agency. The discussion was an even 50/50 split between frontend and backend topics. It focused on general engineering concepts, system scalability, and discussing specific technical problems alongside potential solutions. Round 2: Technical and architectural interview with the Bayer team. The first part was a short algorithmic coding task focused on merging adjacent timeboxes into continuous blocks. The second part involved a system design exercise where I had to plan an event-driven architecture to bulk-create user accounts based on data from a CSV file.

Interview was for 1 hour. It was a mix of both technical, behavioral and functional questions. Panel had 4 interviewers each took time to introduce, explain about the role. Interview questions were real world scenario based and some conceptual.

Total three rounds. Started with technical in which the first twenty minutes will be solving a problem for me it was based on string. Questions can come around the way you implement it. Then it will be a technical scenario based mostly around configuration like Exceptions handling, Authorization etc etc. If you clear this second round there will be more technical scenarios and managerial questions. Then finally the HR round. It is a very good process and not difficult to crack if you are working on these scenarios on a daily basis.
