Feedbacks were awesome. Really like this interviewer also.
I think the key of this system, or anything touching payment, is to have a mechanism to achieve eventual consistency. That's not covered in feedback.
Hey I remember this interviewer from the other video, really good. The interviewer sounds familiar too
The interviewer is amazing.
I hate it when I see people drawing diagrams starting with a load balancer! Those are infra components and can be added later, please start with functional components first.
This is a pretty weak problem statement, IMO. Leaving key functional requirements up to the candidate just brings unnecessary complexity and the actual scope of the task becomes unclear.
How to shard NoSql: Don't they have natural sharding already, by having multiple nodes, like Cassandra?
Basically he was asking what's the sharding key
SUPERB FEEDBACK
42:14 great explain for db solution to generste IDS and why not use it(prople might get same id at this scale
Pre generating 1 mil id is smart alternative, 1 machine can dtore in memory easy
24:45 handle fail of distributed asynchronous transaction , synchronous action
Best Feedback video !! Loved it
The interviewer's feedback is gold. This is another one of his interviews: th-cam.com/video/TUhbXHRLf0o/w-d-xo.html
This is a mock interview. But it was good one.
Very nice feedback!
I have a question about automated system.
great feedback
audio isnt much clear
very good one right here
started out strong and then not so much
How is someone supposed to learn all of these concepts? Pretty insane that SDEs are expected to know of all of the individual services and when to use what/how.
Read a book or take a course over a month or two and you'll learn these concepts pretty quick.. it really is not impossible if so many people can do these type of interviews. just put in the time and effort
Just know basics-- what's a machine, how do they talk, how groups of machines can work together( syncing or async, push or pull)
A lot of pointless questions, implications and mistakes.. Do not take that as an example
Could you advise some better examples?
