this is a true story,

my google interviewer doesn't understand "Object Storage" and interupted me and trying to gave me a hint for "S3" instead of "Object storage". I wasted 5+ minutes just to explain this. I will directly say S3 next time
this is a senior role btw

Yall are actually the MVP/GOAT of any system design prep. When I got laid off in Feb, I was able to secure another role in a top tech company and primarily used yall for my system design interviews. Being able to do practice problems, see run-throughs, and schedule mock interviews with employees actually working at the companies I was interviewing for were so invaluable.

Thanks and keep it up!!!!

I had an interview where they were probing me for designing a system that uploads files through the gateway, not direct to s3 via presigned URL. I think it’s good to talk more about that approach cause companies do have reason to use it

10:53. You can use a multipart upload for objects from 5 MB to 5 TB in size on S3
