Practice your softer skills for interviewing. Do you get anxiety over other aspects of the interview, like the fact that there's an interview itself? Work on that. Many times candidates get hired even if they bombed some aspect of the technical portion of the interview, for various subjective reasons. (Also consider asking for a take-home problem where they give you 2 hours or whatever to email back the solution. It can help if that is solid but your on-the-spot whiteboarding is shaky.)
Also consider an SDET role, those can sometimes be easier to get and then you work internally on removing the T if you really don't like that sort of work.
