Where are the hackerank challenges?

Hi all ,
I’ve received the following email a few days ago.
Hi Benyam,
How’s the preparation for the online coding quiz going? If you haven’t opened up the prepwork yet, now is a great time to do so! Our best applicants usually take the coding quiz in the first 7 days after applying.
If you already have experience coding, please open up the email you received from HackerRank to take the test!
My question is where are the coding challenges?

Apologies I’ve found it, it was hidden in one of my gmail tabs.
