round2 interview

 如泥牛入海，渺无音信。

开始考虑要不要申请其他学校的第三轮了

it doesn't hurt to get your materials ready for other school's R3, just wait till the beginning of March before you seriously considering spending more application fees on R3. Just a thought, hope it helps, plus you might get admitted without the interview, you never know!

exactly

you can mitigate the risk by creating more chances for yourself

everytime you prepare a new application

you'll improve your awareness about yourself and your future career

keep going!
