Asked about some technologies used in projects Basic concepts of OOP

Round 2 (TR) I got interview invite next day . Duration - 1hr Interview started by introduction . Then detailed discussion on project mentioned in Resume. One basic program in Java . He asked me to write code to print repeated letter in string on paper. Query to create table in Sql. Tell me something about your family. What are your ambitions? When did you give elitmus test? Some questions about my hobbies and interests. I asked him about operations of PGS in India. Overall he was a very friendly person and I was not at all nervous in front of him. Round 3 (Puzzle Round) Next day I got invite for puzzle round. This round was proctored and conducted on eLitmus platform. Total 7 question - 6 Mathematical Puzzles and 1 Scenario based question. Puzzles were simple (guess next number in series type). Where do you see yourself in next 5 years? (Scenario based question) Round 4 After 1 day I got invite for fourth round. It was mixture of technical and managerial round. Duration - 1 hr Mentioned(Mine lasted for 0.5 hr) Again interviewer was very friendly. He started with his introduction and then asked me to introduce myself. Again detailed discussion on project mentioned in Resume. Where do we use HTML, CSS, Java, JSP and Servlets? (I have mentioned these technologies in my Resume) Tell me lifecycle of a Servlet? How can we count number of visitors on any website. do you have any idea about it? I want to make an attendance system, in which I want to store attendance of students and in month end I want to show the student who attended maximum classes and also same for student who attended minimum classes . Can you tell me how can you implement this ? Tell me simplest approach? I gave example of sql table and told that if student is present than we add 1 in attendance column otherwise 0. In month end we can use MAX(SUM(Attendance)) to get student who attended maximum classes and for minimum we can use MIN(SUM(Attendance)). Then he asked me a scenario based question. Suppose I give you unlimited amount of fund then what problem you would solve with that? I gave one example but I did not know the implementation of that solution so he told me that give me an example which you can solve by yourself. Then I gave an example of my branch related problem and also gave the solution with implementation. (I am from Electrical Engineering Background) Then he asked Who else do you have in your family and what do they Do? Then he said Ok I am done, if you have any query then you can ask. I asked about technologies they give to Trainee. Tip : When I asked him this question, he asked me whether I have asked same question in first interview round? I told No, then he explained technologies . So never ask same question in interview. Round 5 (HR Round) After 1hr or maybe less than 1 hr of fourth round I got call for final round. HR round was scheduled for next day. This round was just like formality. Duration - 8 to 10 minutes First he asked me to introduce myself. Tell me you two strengths and weaknesses . Then he asked whether I comfortable in relocation or not? ( Always say Yes ) Then he explained about training and other details related to job. After 3 hours I got selection call. Then after 2 days I got offer letter. Conclusion Duration of whole process was around 1 week. (excluding round 1) Prepare your Resume very well because they literally ask everything from your Resume. Round 1 was very difficult, so prepare well for that round.
