Interview Preparation Tips
Interview preparation tips for other job seekers - I may have been working excessively on SQL and SSIS, but I started learning Datastage ETL tool as well. See, the point is how quick learner I am. There are people who are with 4+ in Datastage, but still I have to explain them the flow. Even when the assigned development is completed, I tune the jobs, remove unwanted columns, RCPs etc. I learned quickly and accelerated myself and that’s why my current employer gave me the opportunity to lead. I think everyone deserves a chance to prove themselves. I thought I’ll get a chance here as well but was unfortunate as they saw only those things what were on Resume, it’s better to drill down in the interviews rather than seeing the less experience. People with less knowledge as well get a good package, but if someone wants to learn then the recruiter should give a shot at least. It’s not the concern of package, I even was ready to negotiate as far as possible because I was getting a lifetime opportunity to work on a newer tech, but all in vain.
