Interview Preparation Tips

Round: Technical Interview
Experience: Interview was for 30 minutes duration. They have started with basic concepts like Abstract, Interface etc. Then they moved to core java. Some basic question on core java related to Exceptions, try-catch-finally blocks. Spring MVC basic questions, bean mapping questions. use of tomcat server in eclipse.
Tips: I was lucky at that day.
Interview was more likely of fresher level. I was first in the interview process, interviewer were not ready, so they directly asked few questions to me.
Level of interview was not up to the mark, I prepared for tougher interview, gone thru 500+ questions on core java, spring, hibernate, exceptions and try catch.
0-3 years in java is equivalent to fresher. But you have to be prepared for worst if you really wanted the job.
Before going to the interview, Do hands-on.

How much flexible I am with shifts and work loads.
Tips: Its simple round, You have to be sure why you want this job. give them a very valid reason of your own. Don't copy anybody else's answer. Be confident. If it is on call, speak clearly, maintain pace and voice. They may throw situations and puzzles. be calm, use your mind. Its fine if you don't know about anything. But don't tell directly that you don't know. Try to use all the positive words and phrases.

Round: HR Interview
Experience: They asked some question about myself. about family background. about hobbies and from your resume also, like how many projects you have done.How you are feeling in IT industry. Why this company.
