Open Systems International Software Developer interview questions

Started with a phone screening call that lasted 15mins basic questions. then I heard nothing from them for 3-4 weeks. When they contacted me they scheduled a 4 rounds interview: 1 with software engineering team manager 1 with software engineering director 1 with HR to go over the benefits --> not an interview 1 with a software engineer --> Technical assessment 2 weeks later I got an offer from them
