This might be controversial but here goes...
On the other side of the coin I had an unforgettable interview experience for a role that really questioned my pro-viewpoint on disability in the workplace. Prior to this interview I was a firm believer that anybody should do the job they want and overcome obstacles. Afterwards, ths changed.
Prior to the interview, the recruiter phoned me and said "Just a heads up, you might have a little difficulty in speaking with the CTO due to his disability, but I'm sure you'll be OK". A slightly odd conversation but I appreciated the information ahead of time.
Upon arriving at the conference room the lead engineer (Alice) said "Bob [CTO] works remote and a word of warning - you might have a little difficulty in understanding what he says, but don't worry I can help if you get stuck". That's now two people who have warned me.
Bob had a degenerative illness which made his speech stutter and slur heavily.... to the point I could not understand _anything_ he said. Nothing. It was like trying to understand someone who's clearly drunk more than they should, to the point of nearly blacking out (I'm serious here).
When he joined the company 10 years prior he was perfectly fit and healthy, and within 5 years became CTO of the startup. He was still healthy at this point. All good.
Bob developed illness which impaired his speech so much _every question_ he asked me had to "repeated" by Alice sitting at the table beside me. Every word that came out of Bob's mouth had to be "repeated".
It was impossible to verbally communicate with Bob wihtout Alice present to translate. It took 2 very long minutes to ask "how are you today?" at the interview start. 120 seconds. How was anybody going to effectively communicate with this person on a daily basis or have technical verbal discussions!? If they said communication would be written text only with the CTO I doubt I would have accepted the interview.
To me engineering is all about communication. You communicate ideas in varying degrees of technical depth to cater for your audience, who in turn communicate their ideas to other parties - be it board level, juniors, external parties or even the accounting department. Communication was totally broken here.
What was most concerning was Bob didn't seem feel his disability was serious enough to step down from such a role (or management didn't want to suggest he step down... maybe through fear of law suit?). His inability to verbally communicate anything would have a bit impact on their product development.
The company did ask me to return for a second/final interview (they phoned the recruiter within minutes of me leaving the building..) but I politely declined. It would have been impossible to work with Bob.
