@imter,
Since 26th Feb is the first friday for the "first interview" held, there will not be any final interviews on that same wednesday since no candidates have been selected yet. Sheesh, that was a mouthful.
Perhaps the recruitment people decided to open up the wednesday due to the overwhelming response. This would only be for the time being until the recruitment drive settles and the flow of applicants stabilize. After which, the norm would be friday.
