Citi Senior Software Engineer I interview questions

Typical how-would-you-do-x, and basic technical questions. They completely failed to mention the utter lack of resources, and that we'd have no desks, and would be working at any of 5 different buildings spread over a 50 mile radius on any given day.

I had an interview with CITI corp Pune for the position of Senior software developer(java, j2ee). It was scheduled interview which was referred by one of my friend working at CITI. They had called me in weekdays and interview was scheduled around 2PM. As I went there the HR told me to give the codility test as interviewer went for lunch, though the test was not part of interview process.(This has been stated by HR itself). The test has one java programe and bug fixing scenario, 1. Convert decimal to binary and count number of 1's in the binary number. 2. There was a code written and it has a bug, yoy have to fund out the bug in the code where you can modify max two lines of code. I was confident on the first programme as it has ran successfully with proper output. For second I was not quite sure. It almost took 50 minutes to complete the test. After that HR told me that interviewer is available and you to to give F2F interview. Interviewer started with a design statement like to design the Railway reservation system where user can book a ticket from a source to destination. He has given me 15 minutes of time to design UI screen with DB design. I came with the solution with 5 screens and three table, what else can you do in 15 minutes. Then he started asking me questions based on this design. This drama continues for 25 minutes. Most of the questions are scenario based, like how do you restrict double click operation while booking a ticket. I have given him two solution one is from client side restriction and other we can restrict from server side. But he was expecting the solution which he knows!! Then he came with java thread questions, what is Producer/consumer problem, Executor Design pattern, Semaphore, Transient variable in java. Which designing tools and diagrams you have used while designing an application. What is SOA. This process took almost 1.15 hrs and i was somewhat confident that i will get positive response but HR person came and told me that you have not short listed. HR have asked me to give the interview in other project as they have multiple opening. The guy from different project came with java program and asked on Lamda expression which was introduced as part of 1.8.(even he is not sure in which version it has been introduced) I was not sure and not able to give the answer. He said that he is done with it and asked to leave for the day. He was more worried about the tea break at 5 as one of his colleague is waiting outside and his behavior was so unprofessional. I think interviewer/HR should leave there senseless attitude and give respect to the candidates.
