I applied through a recruiter. The process took 2 weeks. I interviewed at OPEXUS (Washington, DC)
Interview
Too many interviews that included redundant asks. Had multiple rounds only to be asked for writing samples (already provided pre-process) in the final round. Seems they have tons of turnover.
The process starts with a phone interview that includes basic data structure and object-oriented programming (OOP) questions.
The second interview typically covers logic questions, LeetCode-style coding problems, and simple SQL queries.

Question 1
What is a HashMap? What is the difference between a HashMap and a HashSet?
The interview process begins with a phone screen, mostly behavioral with a couple technical questions to assess general competence in the subject matter. Very easy going interview, overall positive experience.
