Interview Preparation Tips

Interview preparation tips for other job seekers - Study basic oops and strong or atleast average in C#, i think thats enough, I didnt get selected, I'm 12 years exp. in .NET and 17 years overall exp., they expect 5-8 years exp. and its due to the consultancy i went for this walkin, the position probably not suitable for me, and I am the last candidate to go for the F2F interview, it was a walkin. So I suggest to go earlier when they are not tired and willing, and they might offer someone who hail from very smaller companies. But the good thing probably would be they probably will finalize on same day.
