Overview: Avaya R&D unit of Bangalore visited our campus at the beginning of September, to hire students for the Senior Technical Associate role.
Initially, There was a shortlisting based on CGPA. Around 120 students were selected to attend the online assessment round.
Online Assessment This round was conducted on iMocha platform with 3 sections.
Each section has 30 minutes time.
- The first section consists of 30 Aptitude questions which include problems from Set, Speed, Arithmetic, Blood Relation etc.
- The second section consists of 2 coding questions.
- Print the nth number of the Palindrome Series 11,99,1111,1991… In which series has 2 rules:
- length of number should be even.
- It should contain only 1 and 9.
- Find the count of the number of zeroes to be removed from a binary number so as to make it start and end with 1.
- Eg 1: 00111 – count = 2
- Eg 2: 0010101000 – count = 5
- Print the nth number of the Palindrome Series 11,99,1111,1991… In which series has 2 rules:
- The third section consists of 40 Technical questions which include a wide range of questions from C++ code snippets, DS, Alogirhtms, OS, DBMS and CN.
Total of 23 students were shortlisted to interview rounds.
Technical Interview: This round was conducted on Avaya Cloud and went around 80 minutes.
- The round started with my introduction and about my projects.
- The interviewer was interested in my DBMS project and started asking questions on table design, choice of primary key and connection between tables.
- Difference between Primary key and Composite key, Different types of Joins were asked.
- Then shifted our discussion to Python, as I mentioned my primary language as Python.
- Asked difference between list and tuple, the importance of indentation, about Dynamic typing nature of Python.
- As the interviewer noticed that I am using Ubuntu, he asked Linux commands for basic operations like move, copy, paste.
- Then was asked to choose any one model between OSI and TCP/IP and explain it.
I was able to answer all the questions and shortlisted for next round.
Managerial + HR: This round went around 100 minutes and 2 panelists were there. One panelist seems to be the director/some higher position.
- This round also started with an introduction and discussion about my DBMS project and AI Project.
- The interviewer asked me to find Sine of an angle without using built-in functions or formulas. As I was clueless, He gave hint by telling me to use Machine Learning to solve the approach.
- I considered 5 angles and trained the Random Forest model to predict other angles.
- He wasn’t satisfied with accuracy. Then he told me to do the same with Deep Learning and Neural networks. I did it using Tensorflow and Keras and trained for some epochs and he was satisfied with approach.
- Second panelist asked to write a program to merge two sorted arrays into a third array and also asked the approach to merge n sorted array.
- As I specified my hobbies as Current affairs and Astronomy, The interviewer asked me to explain a recent event in those fields.
- Asked about my family.
This round also went good as I was able to answer all questions. I asked a question about their cloud platform.
Results were announced, only 2 students were selected and I was one among those.
Tips:
- Know in-depth of any one of the programming languages like C++, Java or Python.
- Know about each and everything mentioned in the resume thoroughly especially Projects and Internships.
- Solve all the important DSA related problems in GeeksforGeeks. It helps you a lot.
- Prepare for theory questions on DBMS, OS, CN, and DSA. (Theory learnt from college subjects are enough)
Thank you GeeksforGeeks for its tremendous content which helped me a lot during placements.
All the best 🙂
