The contest lasts for two days, prizes worth $11,000.
Previous women's contest at Hackerrank lasted for a day, contestants' level was rather high: all the tasks were solved by more than 100 persons, though it wasn't that easy.

Lasts for two and a half hours, top-150 are invited to attend Google I/O conference.
Last year's tasks were easier than those at regular GCJ qualification round. I guess the contest was poorly announced, so it lacked participants, all the tasks were solved by 14 persons, and to reach top-150 it was enough to get 45 points out of 100.
Good luck!
