It depends on whether the OP is failing tech screens or whether it's the companies/interviewers that are failing the screens. I was on the job hunt earlier this year and, while I'm by no means perfect, I had a lot of tech screens fall apart because the interviewer was awkward, pushy, or arrogant; or the demand placed upon knowledge or skill assessment was unreasonable. My impression is that if hiring really mattered to these companies that they would refine their hiring process rather than leaving it up to whichever dev who has nothing else to do that day.
