You need real experience. Preferably with safer species. Get some Correlophus and take them to the max' potential. Maybe, once you become rich and gain experience, you can afford to take venomous handling classes, maybe even get licensed or permits.
We've already been there....to no avail.

A month-long externship is a start, but depending on what you actually did, usually nothing to write home about.
And @Nikola: it's "my [opinion]", not "mine" - like in "MY pipe dreams" or "I should rather focus on applying for the funding of MY PhD thesis than waste my time online entertaining others with MY antics".
The monotony you mention @jayjds2 is actually one of the drawbacks of the "stamp collection"-style of zoo presentation. Unless you're a taxonomy fan (or a zoochat rare species geek), you'll soon find yourself exhausted after rows and rows of similar looking exhibits, and stop paying attention. Modern presentation forms, however, aren't perfect either; their increasing standardization makes new exhibit complexes and enclosures look like dull clones, copycatted from one another, while the "green space" actually takes away space that could have benefited animals or staff.
