Slack interview questions

Initially I interviewed with Slack, but ultimately stopped mid-way through the process due to receiving another offer elsewhere. Was wished well, and all was on good terms. 2+ years later (about 1 month ago) I applied again for the same role, now having another 2+ years experience. Within a day or so of applying, I receive an automated/template rejection email. I'm a little shocked to be completely honest, as my skills & qualifications were a perfect match for the job description 2+ years ago (and based on the job outline, they are still as such). The interviews had also gone really well with the recruiter, and responses to the task were on-point. I'm a stickler for good CS, and it's a passion for me - not just a career. It's a bummer, because I really do want to work for Slack, it's a great company, but unfortunately I can no longer make it past their AI system since being acquired by Salesforce I guess. One thing I did notice is that their education drop-down in the form you need to fill out (with all resume elements...) has a minimum option of bachelors degree, and doesn't allow you to input college diploma as an option. This is hugely discriminatory and classist, as not everyone can afford the money and time required to obtain a degree, but this doesn't always mean that they're not experienced for the role, nor does it mean they lack an education or the drive to be successful and thoughtful in the role. Very sad to see this, especially since I know myself that I'm great at what I do and would have been an excellent addition to the team.
