IBM Developer interview questions

I have given 2 technical round in which in first round discussion about my resume and projects are focused and in second round I have to write 2 codes one is easy and one is medium.

Submitted the application and I got an assesment to do, there were two questions and I passed the first, but second question I only passed 6/15 test cases, After that didn't hear back, in the portal it says "Assesment in progress".
