General Technical Questions (No specific Scala questions). Software Development Cycle Questions. White Board problems (two).

1 réponses

Just google Java interview questions. They are very inexperienced in Scala. Just be aware of standard dev cycle concepts, such as continuous integration, continuous delivery, SCRUM, story/task estimate methods, etc. Won't give the white-board problems away, but they are pretty standard. Google for the classic ones. They are not strong on algorithms by the way. They probably Googled for a couple just for the interview. They seemed not to understand the problem they were inquiring about very well. Moins
