Clarifai interview questions

All the interview rounds were good and I cleared them all, but unfortunately the mail i got as always what i expect from the organisation’s is like we have frozen the hiring, we are still in process, we need time to think to take a proper decision, we have withdrawn this position or we have kept this position on hold. It has always been a disappointment while you have spend so much of your time and efforts to prepare for the interviews and learn about the companies product/platform, and you clear them all and at last you will get a response which you have never expected.
