HeavenHR Senior Java Developer interview questions

I have applied through StackOverflow. I got scheduled an HR Call which is related to salary expectation and my experience. Second, I got an assignment to complete within four days. I spend around 15 to 20 hours to complete. If I am talking about assignment basically it is Restful API. Third, Around 1hours technical interview. Question about Microservice, Hibernate Transaction, Java8,Restful and Collections.

I liked the interview with HR. Unlike other interviews there was a simple question on the gumption and basic math. However technical interview disappointed. The interviewer did a lot of "strange" statements and questions. For example he asked if we used Apache Camel as ESB and said that they use Cucumber for integration testing. I came to the conclusion that they either may have a weak team in terms of knowledge of the correct use of modern technology stack or this is kind of "puzzling" interview where the interviewee should always disprove interviewer statements or he would not fulfill the test. The latter can say about other shortcomings, such as "blind adoption" and "one truth" about fashion concepts in the team. I did not pass the interview and they called as reason that despite of my great skills their developers decided that I didn't fit the overall profile of a senior developer, what they're looking for. I guess the company which is transparent and respecting their candidates must give a more meaningful answer to the question.
