I have taken interviews from a lot of the top tier companies and they don't really care what school you went to, your scores, or even if you graduated from college.
This will help you a lot more than certifications:
_ Get a github account
_ contribute regularly, open source projects are good, if you can get a few projects of your own too
_ if you are a developer
- go to leetcode/careercup/interviewbit and do most medium/hard interviews in your language of choice (python in most big interviews)
- there is always an easy question: invert an array, string, search
- there is always 1 question with linked lists, graphs, trees
- get familiar with o(n) algo complexity
- do lots of problems, learn to do it on a whiteboard, it;s about doing it fast with minimum mistake, practice
_ Look up behavioral interviews
- be familiar with the star format
- get familiar with the classic questions like "imagine a time you were overruled"
- get multiple examples and response with all components of star format
- practice saying responses, maybe with partner
There are a few companies that will look at certifications: (1) contractors, mostly government contractors to fulfill a role (2) staff augmenting companies.
but as a general rule, the most use I have had for certifications were for guiding learning and learning the vocabulary/process necessary to talk to stakeholders who did. They never prevented me from getting any job
