I have done my java course from Sky. Trainers and course material were all fine but they delayed my placements.
I was told that I will be placed immediately after completion of course. Sky Infotech provided me placement but after two months.
So, I will suggest that if you can wait for 1 or 2 months for job then join Sky infotech because I did not like that I had to sit at home without job for 2 months. This was my major problem but later I got job and I am in a good company now.
