how spark strucutred streaming works internally
Only related to projects I has worked.
Mostly about whats mentioned in your resume I had questions on Angular JS, REST API and Services
Explain database lookups.
Design and coding questions.
Do you have any questions about our business?
The first part of the interview is a video code-pairing session. You need to know ECMA6 and promises very well. That's all the test is about. You get thirty minutes to solve three problems related to asynchronous requests and timeouts. There were so many issues with this test, though. First, these are terrible conditions to code under. Second, their own poorly written code was throwing so many JavaScript errors that the console was useless. Third, they included a function that was never used to solve the problems but consistently threw me off as I tried to figure out how to use it. Fourth, at the end of the session, the engineer admitted he didn't understand why the first problem was solved by solving the second and third problems, but that's just how it worked.
The second question on the take home exam is completely disrespectful of a candidate's time. In four hours, they expect you to add three significant functions to a JavaScript/HTML 5 drawing program, fix existing bugs (you have to find them), and then refactor their code. The solution requires writing several more algorithms. It's a project that no one would ever have to complete in four hours. After the test, an engineer followed-up asking me to benchmark my algorithms and explain how I would improve performance. The algorithms performed within fractions of milliseconds at high load. Why would any engineer waste their time trying to shave fractions of milliseconds off their code?
Most questions were about technologies and several problems to solve.
