I never had much problem with applications in the last, but in the last job search it was futile. I’m still just now getting rejections from jobs I applied to months ago which seem a perfect fit for my resume. I even applied to a place I worked a ~5 years ago, which I got via cold application. Apparently I’m not good enough anymore because I couldn’t get past the filters. I finally found a job through a referral. Oddly, it was working with tech I have basically no experience in and probably had the most awkward interview out of all the ones I ended up doing.
