I applied through a recruiter. I interviewed at Collabera (Seattle, WA)
Interview
This is a L1 interview conducted by Cogbee and focused on the basics of Java, SpringBoot, Micorservices, AWS, Kafka, SQL. Pretty much basic concepts in core java, java 8, spring core, spring boot, mysql, kafka etc. Asked me to write sample code using @Transactional in Spring.
A total of 35 to 40 questions were asked purely focusing on the fundamentals of the subject. If you are good at basics, then no need to worry. You can clear it easily.
All the best to everyone out there!
Final Result: Able to clear this round.

I applied online. The process took 2 weeks. I interviewed at Collabera (Bellevue, WA) in Nov 2013
Interview
Very easy interview. No algorithm questions. A recruiter called me and told me about the position details. Then he arranged an onsite interview after a small online C# and ASP.NET test. I talked to one PM, two SDE's and Team Lead and they asked a few questions to test my knowledge.
