Had a online test with them after sending application. I guess thats the way they filter out applicants. The test had two parts: 1. giving you an imaginary programming language description and you read it then you answer some questions on that. 2. Java questions. I would say try to prepare by reviewing some Java books.
Interview questions [1]
Question 1
I used to program by just looking up Java api online, but I couldn't check any online reference, so I would say try to get familiar with Java api as much as you can.
Medium level leetcode and then a very basic system design question as a final round interview. Overall, smooth and simple process. Only one technical and it was the first one.

Question 1
How would you design a system to minimize wait time at a health care center?
First round is a thirty minute phone call with one of their developers. The other part of the first round is a three hour exam with IQ test style logic questions and coding questions.
[OA] OA was fair. Programming part are leetcode easy and easy-mediums, straightforward simulation, backtracking, dfs, strings, etc. No DP/graphs but ymmv.
[Final interview] (Case Study) I think the interviewer came up with their own prompt. It's mostly discussion-based, with a virtual white board. It's not too technical. I'm guessing its testing your communication/logical reasoning than system design skills. (Pair programming) 1 question, same format as the OA on the same platform, leetcode easy.
[Overall] Technical difficulty isn't bad. Interviewers who are current software devs seemed friendly. Had a good experience, yet got rejected.
