Interview Preparation Tips

Round: Technical Interview
Experience: I got the interview scheduled via a consulting firm. It was on a Saturday morning hours. I reached location at time. There were 25 candidates for my profile. The office interior was just out of this world. The lift system was the most technologically advanced system I had ever seen. First round was taken by a senior guy, who was very good in technology. Second round was managerial round, asked more questions on my last project architecture and why I chose the technical stack used in that project. Basically had to tell the significance of MVC, bootstrap and AngularJS. Last round was HR round and had basic HR questions.
Tips: Prepare well on OOPS thoroughly, advanced topics on MVC and basics of WCF and WebAPI.

Round: Test

Round: Group Discussion
Duration: 15 minutes

Skill Tips: Infosys Internship program is structured very similar to Infosys Foundation Program. In both programs, the course is divided into two parts -
Generic Training and Stream Training. Generic Training will be based on Computer Science' fundamental subjects like OOPs using Java, RDBMS using Oracle, Software Engineering, Internetworking and Operating Systems. Stream specific training will be based on a certain technology like J2EE, DOT NET, Mainframe, SAP etc.

If you're unable to pass the internship program, you can join Infosys as a Systems Engineer trainee after you complete your engineering course and can undergo Infosys Foundation Program. Accommodation is free while going through internship program. You need to pay for food and for other amenities like Gym and Sports facilities.
The monthly stipend during internship program is INR 8000. Advantages for opting internship program is Infosys internship program would help you to undergo the initial training course while joining Infosys. So, if you successfully complete the internship program, you need not to attend the Foundation training in Infosys. So, when you rejoin infosys after completing your b.tech course, you would join as an employee, not as a trainee. It will help you get into production much advanced to other people who go through Foundation Program. After you complete your engineering course Infosys will communicate you with a date to rejoin the organization.
After you complete your internship and get posting location. When you rejoin Infosys, you have to report to that office only. Need not to come to Mysore or Mangalore again for reporting.
Once you join for internship program, you have to sign a bond and if you do not opt to rejoin Infosys then you need to consider the consequences as per the rules written in the bond like paying some amount.
One advantage of successfully clearing internship program is that you need not to go through Foundation program in Infosys. Both have equal weightage in Infosys. Scope of learning is same in both type of training.
