It gives you ticket to advance in your career, but it will only give you some short term attention of your superiors. Without passing 2nd na 3rd level you are just a guy who can’t finish stuff. This is true, so it maybe makes sense not to mention it in case y ou don’t plan to continue.
and I forgot to mention, it brigns also great girls in your company. A lot… LOL
I don’t think so, which is why it is useful to update your LinkedIn and make it all public. There is a feature where you can see it as the public will see it. Take off any information that you don’t want people to see and leave the rest out there for recruiters to see. I get at least one email every few weeks from recruiters. I like my job so I don’t usually follow up, but real recruiters are on there looking for people.
Make sure you follow the CFAI standards for updating your status. Good luck.
