政府會再screen gayao!

For me last year I got the nomination from my university around the end of Feb, then received offer from CSB around end of April. 

Even though it is possible that CSB can screen nominated candidates out, it is very unlikely that they will because your university center select candidates for nomination to CSB very merticulously. At least from my experience and from friends that I know, failing to receive the internship offer after nomination has not happened so far.
