Path to career in bioinformatics?
The Bioinformatics Stronghold at Rosalind is an excellent resource for building your understanding of many concepts and algorithms you'll see frequently in bioinformatics and genomics.

I'd also say that, if you can make it work, an internship where you can "get your hands dirty" with real problems is a very valuable experience. This option may not be available to everyone due to a variety of factors, but when it is an option it provides a tremendous opportunity to build experience with little risk to the intern or the employer.
