Infosys Interview Experience for Specialist Programmer

I am dividing the complete experience into two parts

• All about Exam
• Interview Questions

So let us begin with the first part is how you can apply

All about Exam: There is a certification round of Infosys in which the third-year students can apply. So I have applied for this and started my preparation accordingly. You can apply in that round with one of the following languages Java/Python. I have applied with Java.

• The certification round was held on 8th February and I was a little bit nervous because I know C++ but the exam was in java so I know the basics of java only my slot was at 10 a.m.
• In that round, there were 20 MCQs which were divided into two sections 10 from Java and 10 from DBMS. Which have applied through python they got the MCQs of python instead of java.
• So I have solved approximately all the MCQs and there is no negative marking in this.
• With MCQ there were 2 coding questions as well which I have to solve using Java and I have solved 1 question 100% and the other one 50%.
• The weightage of coding was 60% and of MCQ was 40%.
• The cut-off for this is 65%.

Result:- So within one month I got the result within I month that I have cleared the exam. Based on that exam, you will get an interview mail for the system engineer role.

After clearing that round you can appear for the advantage round and If you did not clear that round then you can go for the hackwithinfy exam means you can either give advantage or Hackwithinfy If you clear certification then you can not give hackwithinfy you can give advantage round Only.

Advantage Round: My advantage round got scheduled on 7 March. In this round, you can get an offer for 2 profiles 

• DSE Role
• SP Role 

You will get the role as per your performance in the advantage round. In this round, you will get 3 hours to solve 3 coding questions and you can solve the questions in any language. I have solved 2 questions 100% and 1 10% using c++ and the question are related to the array, hashing, and Dynamic Programming. (Reason, why I was able to solve the question, is Geeks For Geeks I have practiced a lot of questions and read a lot of articles at GFG)
