Well, from your screenshots, I can't say for sure, but here are Things To Check:
The exact match is exact: no query parameters or ending slash on the visited page, no trailing spaces in the goal definition. You could see whether changing the match type from "Equals To" to "Regular Expression" fixes the problem. Unless you have another page that contains the string
/welcome-candidate/success and shouldn't count as a goal completion, regex should be fine to use for the goal definition.
The goal is active: definition saved, and Recording set to On. Recording may turn on automatically when you save, but I don't remember for sure and would double-check it.
Other things I think about but probably aren't the problem, included for completeness:
I usually switch to the Last 30 Minutes display in Real-Time, because it shows more information than the Active Users display, but if you're checking immediately after visiting
/welcome-candidate/success that shouldn't matter.
Filtering out one's own traffic can be an issue with this sort of data, but if that were the case you would also not see the pageviews showing up.
