I’m also awful at interviewing and this last time I just went all in on practice, paying for advice, and practice, an unrelenting amount of studying and coding. I hated it for weeks and then after a month or so I started to enjoy the drills, like exercise or something. Either way, all the practice paid off, I encourage you to just try 175% harder than you think it’ll take, if you can. I’m not a CS major, I hate l33tcode, you can do it too… and then negotiate like a champ.
I can totally relate to that feeling but after a few rejections, and having to work 9-5 during the day and prepare in the evenings with a drained battery, it just totally kills the motivation.
Maybe it's the type of circumstance when if I'd really need I could do it, but to try to "suffer" through the process just to be rejected is quite hard.
