Actual interview

Step 1: We were asked to write a 100 word write-up on ” Your greatest strength (s) that would help Verizon”.
The interviewing team introduced themselves.( there were two people – One person was asking technical questions and other person was asking HR questions) Both were asking questions alternating.

They went through my write-up, and the HR person asked me an hypothetical situation

” Assume you are working on a bidding . You quote a price after lot of analysis. At the last moment your boss says that you should quote a lower price. what will you do”

he kept asking subsequent questions to corner me and was focused on making me accept that I did not have the quality that i mentioned in the write-up.

Technical person asked me what I was comfortable with C, C++ or Java. I told Java.

1.     Instances where I have exhibited my leadership qualities?

2.     How do I motivate my team members?

3.     What is my biggest achievement in life so far?

2.     What I have learnt in college or what the college has taught me apart from subjects

The technical person asked me what other subjects I have learnt so far in curricular and he interrupted me when I said “Software quality Management”

The HR person took over and asked me one last question
