Interview Preparation Tips

Round: Test
Experience: Firstly CGPA cut off was there of 7.00. Then Written Test (Aptitude, Quantitative, Verbal, Reasoning, Technical, 2 Programming questions) by Aspiring Minds. (around 65-75 students).
Written Test was of 126 mins and each section had specific amount of time and some minimum number of questions were compulsory to be attended in each section.
Approximately 1 question had 1 min 15 seconds time. Time limit was there for each section and not for each question. Programming section had 45 mins - 2 questions(not very tough, different questions for all but moderate level only).

General Tips: Be prepared with at least one question to be asked to the interviewer at the end. Highlight networks and if you are interested to work in networks then express that to them.
It was overall a good experience. I was the first to be interviewed and unlike other companies HR and technical interview was held for all the candidates one after the other only and people didn't had to wait whole day for interview to happen. Interview was short i.e around 15-20 mins for each candidate in HR as well as Technical.In HR be prepared for why you want to join ALCATEL? (with a different answer, not a regular one).
Skill Tips: Subject books for Network, OS(Wiley Publication), DBMS etc.
Focus on Networks, OS, C/C++. Try to highlight your projects that you would had done in the field of Networks, Distributed Computing, Hadoop, Big Data. I was asked questions towards networks, about projects, Big Data. Difference between C++ and Java and Python. Which one is better, where, why, etc. Memory Leaks. How we get broadband in our home? I and some of my friends had technical interview and none of us were asked about linked list, tree, queues, Data Structures, but other technical interviewer was asking about them. Must read about the company before attending interview. Must attend PPT to know bout the company.
