"For quite some time we've been grilling our candidates about dirty corners of TCP/IP stack. Every engineer here must prove his/her comprehensive understanding of the full network stack. For example: what are the differences in checksumming algorithms between IPv4 and IPv6 stacks?"
I read that and was blown away, uttering "Bloody hell."
I would have never known that from the top of my head. Good joke, well played, sir.
- mauricemir 11y agoWhat you really need to know the dirty little secrets of the various implementations of the stacks and the short cuts (or blatant ignoring of standards). My Boss at BT could do this from a x.400 packet trace and point to the offending dword and say that is XXX's POS stack. There is also the story of a guy (at BT Labs) who took the CCIE and only scored 98% he then wrote a personal letter to John Chambers explaining why he was right and Cisco was not. ... Turns out he was one of the 3 inventors of Ethernet
- Achshar 11y agoDo you have some link where I can read more about it? I googled but nothing came up. The part about the CCIE.
