AWS SDE-2 Onsite interview help!!
I have an amazon interview coming up in 2 weeks. Will complete grokking the system Design interview and have been working on LC related to Graphs, Trees and a few other data structures!! Need pointers in preparing for Graphs and system Design to be honest!! YOE - 5yrs And some behavioral question tips as well Any help is really appreciated, since i am nervous af!
For behavioral, prepare scenarios from your previous jobs for frequently asked Amazon behavioral questions in STAR format. Also, prepare 1-2 scenarios on each of the Leadership Principles.
Awesome!! Thanks for the pointer dude. Appreciate it
Make sure you know how to parse a Roman numeral to an integer
Wow!! I too had the same question in my phone screen for AWS đ I hadn't seen it before and wasn't that quick in solving it during the 25 minutes, so didn't make it. đ
cool!! will prepare đ
I perfected 2 coding rounds, marginally missed on main system design round LLD. HM round was system design, I did good. BR round was system design HLD, did good. The system design round is taken by a sde2 guy with fair amount of experience who ask real life problems the kind they face. Expect a very neat solution in limited time. Don't underestimate their judgement standard. Bar is high on System design as I was told by recruiter that even if I missed in one of the coding round and did system design better I would have been through.
Awesome!! I appreciate your help and time spent on telling me so much about your experience in detail. Would you mind telling me the exact question on LLD and HLD? Just want to understand the difference between LLD N HLD!! Also where you study those from?
System design main round: Design a promocode service, their interest was in low level details of how such a generalized service can be built which can be used by the teams inside or even could be sold to outside orgs. Bar raiser: Design a video distribution platform. This was asked because I had worked on a similar product. Handle the case of upload of huge volume of data, how would the system need to scale. HM: "Design/Add a service in e-commerce platform that gives frequently bought together items" How the service will integrate with the rest of the system, service APIs, low level schema, then scale it.
First of all relax. Try to finish as many problems under Amazon company tag on LC sorted by frequency. Go through Grokking but donât try to by heart solutions. Course teaches you about what you should do when you are dealing with particular type of problem. You wonât get exact one in interview but you would be able to apply your knowledge. Good luck.
Yup. will keep that in mind! btw how much of object oriented design would be needed?
1 round will be focused on system design
Brush up dynamic programming skills as well
from LC or any specific source u recommend?
LC is good enough, in fact I hear LC is absolutely enough for amazon
