Hey guys! I've been working with Atlassian tools for more than 10 years and I know how important is to hold at least one Atlassian certification when you decide to get a fulltime job on Atlassian environment as Consultant/Admin/SysAdmin.
I have put together a blog post to share with the community my experience taking all six exams and what I used as baseline material.
I hope it helps you to get the job you really want. :-)
I'm glad to discuss here or on the blog post any additional questions.
