Hello everyone, Chandan from this side, in this post I shared some of the best resources and strategy for incoming SE, SES, and PP interview and even for TCS Interview too.
SE → Software Engineer (3.6 LPA)
SES - > Software Engineer Specialist (5LPA)
PP → Power Programmer (8LPA)
This post is divided into 3 parts -
1 . Core CS Subjects
For all of three u have to prepare core cs subjects like CN , OS , DBMS , Computer Architecture Basics, OOPS , but how?
-
Resources for OOPS (c++ , Python , Java )
This is very common they ask u on the basis of language u written in Resume.
`
`
-
Resources for DBMS / MySQL
This subject is very important they ask anything either very easy or in very deep so prepare well and especially SES and PP guys u have to be more careful.
If u have time then u can watch main topics of DBMS Sanchit_Jain_sir
`
`
-
Resources for OS
This subject is also important they ask very few questions (rarely to SE) but high chances for PP.
`
`
-
Resources for CN
Mostly they ask few questions for PP role .
`
`
-
Resources for Computer Architecture
They ask very few questions for PP role (rarely for SE and SES )
- What are Flip-Flops?(Most common, may be asked for all)
- LINK
- Revise Cache memory , pipelining etc.
`
`
-
Resources for Software Engineering
They ask at least a question from this.
- All software development models and cycles.

2 . Coding / DSA
-
For SE
For SE they ask very common questions.
- Prime Number , GCD
- Reverse a Number
- Reverse a string
- Bubble Sorting
- Reverse array
- Fibonacci
- Factorial of a number , and so on ( basically I gave u some rough idea)
-
For SES
For SES they ask medium questions (included above too)
- Prime Number (Sieve)
- Pattern Printing
- Fibonacci (without recursion)
- Factorial (Without recursion)
- Max contiguous subarray sum
- Merge, Quick and Insertion Sort
- BFS / DFS
-
For PP
For PP they ask some advanced question too (included above too)
- Revise all traversals ( Zigzag, In, pre , post , level etc)
- Sum of all subarray of an array
- Reverse linked list
- Find whether a loop in linked list
- Find whether there is a cycle in graph
- Implement AVL tree.
- Coin change problem.
- Heap Sort
- Graph coloring Problem
- shortest path in graph ( if u don’t know implementation just tell them thoery , Prim’s and Kruskal)
- Insertion and deletion in BST ( U have to write code)
- All views of the Binary search tree.
- Knapsack Problem
- Water Trapping Problem
- Inorder successor of given node in BST
- Next smallest Palindrome
- Array sum using recursion
- Matrix rotation 90 degree.
I gave u some basic idea and some questions they asked the previous year . (google all above)

3 . Resume / Projects / HR questions
-
Common Tips for all -
- Prepare your project very well, If u do not have a project I would suggest preparing a small project in this time duration remaining.
- Prepare your resume, go through it, and write only those things which u really know.
- Prepare all basics HR questions, like , why we hire you? blah blah.
- If u r disagree at some point be polite, and be confident, don’t be arrogant, sad, overexcited … a smiley face is sufficient.
Hope my above article helps u to clear the interview process (SE , SES , PP ) . 
Till then Practice fking hard, Because -
When u r not practicing someone else is ,
and the day you meet them u will lose.
PS : If someone read who also part of previous hack with infy can share their experience below in the comments. If u have any doubt let me know, If i m able to solve I will surely help
EDIT : After the guidelines of infosys regarding interview two topics also added -
