Both SWEs and SAs get system design questions in their interviews but should there be any difference in their responses and approach ? What I'm trying to understand here is should a SWE focus more on database design and estimating users etc and SA more on Infrastructure architecture ? Or should the response be completely identical ?
No Solution Architect is different from SRE, Solution Architect is pre- sales/GTM Technical Architect.. basically your first point of contact for a customer or partner.
Solution Architect might mean different work for different companies. Did you mean SRE instead?
