in general software engineering has no barriers to entry officially, and it pays well, so you get an influx of people who are all about the $$$ but without any of the requisite skill. I've done my fair share of interviews on the interviewer side to know that there are definitely qualified applicants out there but you have to wade through many not so qualified applicants. People complain about leetcode style interviews but when you get a lot of applicants for a position who are unqualified, you have to filter them out some how.
