Can folks of GV help me make a decision I'm quite conflicted and need some guidance.

So, I'm a fresher with bg is Cs not able to get a job from last year October had co-founded digital marketing agency with friends and then closed it because of not being able to make any revenue learnt a lot from it.

Now I'm thinking of doing Microsoft AI-900 certification and then start applying for jobs or should I take on a sales job.

I'm conflicted here I had graduated last year in July and would love to get your help on this.

Thanks in advance
