Target Senior Engineer interview questions

First round was haker rank with some aptitude and some programming questions , They was asking what they was working on (kafka and cassandra) in details, i am feeling interviewer was not having much interview experience because in interview you should not ask question on which person have not worked or it is not there in his profile, so worst interview.

its very length process, On March 2019 recruiter contacted me, and pre screening call, then a 30 tech interview with sr manger (some foolish questions). then a test case(that you can find in google for solution) and 3.5 length interview with 3 tech and 1 managerial. the attitude of those people are very bad, they are thinking they know every under this world. they even don't smile.. poor attitude.. every time they are doing sometime in there computer some people were sleepy . questions were basic java question and basic logical / design questions. they always use the abbreviation in the question.(some time you will get confused) funny thing is they only know the abbreviations. its waste of 12 hours of case study work and 3.5 interview.
