SAP Labs Technical Round Experience 1. The round started with a brief introduction about myself. 2. In data structures I was asked to write code for height of a tree and Given a binary tree delete  a level and replace the parent node by child nodes, I was asked only the logic for the second question and I answered based on inorder order traversal. 3. I was asked to write code for level order traversal. 4. I did a project based on stock market prediction using random forest algorithm. Questions were asked related to the project like which environment you used to develop the project ( since its related to machine learning we need to handle a huge data to get accurate results , that's why they asked that question ), How random forest  algorithm works?, What are the attributes given for the algorithm, What is the accuracy of the algorithm were asked. 5. UML questions regarding concepts like aggregation, association and composition were asked. they wanted me to draw the ...

Placement Preparation:   I started refreshing my programming skills from december (after my 7th semester internship) by solving problems from hackerrank ( my hackerrank profile ). I started my intense preparation from may. I followed the IPL schedule , given by our seniors. Though I couldn't able to cover all the domains listed over there, I have concentrated on programming tasks since I had Data structures as my area of interest.   I have uploaded the programs and concepts ( problems drive link ) and posted a part of it in this blog . SAP Interview experience:   There were 5 rounds   1. online test  2. Technical (panel)  3. Technical (Face to Face)  4. Managerial  5. HR 1. Online test: SAP online test  In the two programming questions I have solved one question (6 out of 9 sample test cases passed) and did mcq quite well.   The test was attended by 500+ students. They shortlisted 18 students.  I got shortliste...

Date of visit: 30.7.2018 Criteria: CGPA 7 above No current arrear Platform: Hackerrank Duration: 1.15 hrs Overview:    There were 25 MCQ's based on fundamentals like OOPS(both in c++ and java), computer networks, Data structures and Algorithms and also Arithmetic aptitude questions (probability, time and work..). There were different sets both the MCQ's and programming problems were either completely different or shuffled. MCQ 1. Given a circular queue how many additional pointers are needed to perform enqueue and dequeue in O(1) time.     2. Regarding method overloading and method  overriding. 3.
