An online tests which requires a bit of time (quite laggy as well beware) for screening, an hr call short one no significant questions, pair programming coding test, interview with senior developers where a whiteboard coding exercise is involved and you talk about your projects and finally management interview by team leaders.
It is the same EventManagement System that other reviewer has mentioned. So 10 mins before the scheduled interview, the interviewer will email you the source code and a one page write up on the class design. I downloaded the source code and loaded the maven project and went through the code so as to have some idea what it is about. The interview went as follows 1. The interviewer asked me to look at the specific API and highlighted some missing feature 2. He asked me to write a unit test to show that the feature is missing (test fails) 3. I am supposed to implement the feature and make the unit test pass. I managed to write the unit test quite quickly but I spend quite a bit of time in trying to figure out what to do. I had no idea what should I do (maybe my brain was not working fast enough). The interviewer gave me some hints on some possible option I could do and that helped me to figure out what is the solution. I implemented one of his idea and then made sure the unit test passed. That was the end of the interview. Unfortunately, I did not pass that round. They did not like that I took so long and did not experiment anything. They did not like that I had to be give some hints. In addition maybe due to my panic mode I did forgot how to extract only values from a map (They told me I could use google at the beginning of the interview maybe I should have done that). I am not sure I have any advice on this round maybe all I can say is that hope that your brain work faster than mine :)
All questions were easy, nothing difficult. The main goal is to understand the full hierarchy of classes and how Events-EventListeners-EventManager is working together
I didn't feel as though any question was difficult, but I needed to go more in-depth on some of my answers to their later questions.
I was also asked to solve a few coding problems and explain project architecture. The process was smooth and well-organized.
What is a problem that you solved in the past year that you are proud of?
