No, and I had the same responses. I applied at 12 Solutions Architect roles, and 1 company replied and offered the interview process.

I actually don't know how people choose Solutions Architects. One tipp would be to go on LinkedIn, look for the Solutions Architects at the company you apply for, and ask them how they got hired or just look at their CV.

Right now it can be that the market is dried up and this sales role is especially hard, since many fields don't have active customers any more (or won't get new ones in quite some time)
