Citi Senior Java Developer interview questions

:I have applied for almost 9 times in citi company portal.luckily I got call after those many attempts. I got call from HR on Friday 9AMIST. HR was very friendly and good. I have been asked to provide suitable time for interview and I have given the same day 4 PM IST for first technical round. First Technical Round : They have asked all the internal implementations of collections and other stuff related to spring voot and microservices. They have concentrated more on Core java topics like collection, threads and other java stuff. Interview took about 40minutes HR called me after 1 hour of the interview and told that I have been selected for next Technical discussion. That has been scheduled on Monday 3PM. Second Technical Round: Sam they have given some scenarios and implementations in Java. Actually they will test In depth java knowledge. And some things about my current project and technologies. I am currently working on spring booot and microservices. It also took around 30-40 minutes. Hr called after 30minutes and informed that I hav selected for next round.and next interview is on Tuesday Techno Mangeral Round : now this interview is with senior manager. He is fully technical person. He has asked so many questions on my current project and technical stuff. And scenario based questions(technical). It took 30minutes Immeadiately, Hr informed that I have been selected and asked for the documents. I have provided all my documents on Tuesday and I got call from HR for salary discussion. They have given better salary more than i have expected. Final offer letter came on next Tuesday. The whol process took for me is 10days.

Basically they will directly go with direct f2f interview. totally 4 rounds of interview out of which two technical and one was manager round followed by HR round. Please don't go for City as they are now a days only timepassing with employee. majorly every saturday they call lots of employees and go through interview process.If candidate clear the interview then HR do negotiation of package as well. Then they will collect documents from you as well but no offer. Very unsynch hiring status among their HR's. Very unprofessional process after keep you waiting for more than 2 months they said salary is high. They prooven false to their HR as well. I would suggest dont waster time for this unprofessional comp to which they call brand. they are not at all brand. This situation has happened with many guys so keep this as last option.
