准备好cheatsheet，
简单的问题都能回答了。
涉及到design的，troubleshooting的，就是有面经，也不见得回答得好
这个和马工还是差别很大的。 | w*f
发帖数: 111 | 2 agreed. for some reason, Employers always asked "book/theory questions" such
as STP, OSPF etc...
I usually present a network diagram and ask for "how to correct config
because we had issue X" | t*******r
发帖数: 3271 | 3 就网络现象分析配置问题也不是很难吧?
学院派的问题能回答出來, 也不简单. 如果没有那些协议operation的基础, 具体化的
故障你还能分析出来?
扯淡~ | w*f

本人讨厌纸上谈兵的networkers.
we had to fire a few new network engineers who did well in the interviews (
all theory questions). Our reflection was we failed to ask "real life
questions"
You need to know protocols but you need to know "how protocol work" such as
tcp 3way handshake, not "how many bytes" in field xyz. (you can easily
perform google search)
It's good to know "theory" but I hate to see some people who remember a lot
of from CCIE books then believe they're good networkers. Or someone old-
timers bragged about "I can make T1 crossover cable" (I can order them from
local stores so who cares?)
Cisco certification is great but may take some blame for producing a lot of
"paper network engineers"
In my line of work (engineering and Operation in Enterprise), I need to work
with people who had "field experience" and can easily pick up new skills.
The other one is good personality and communication skills.

发帖数: 3271 | 5 说得有些道理, 估计你敲不了中文吧
1, 我也承认, 问哪些个bits/bytes是有点儿傻, 但一般这种问题我只问一个, 99%还是
实际操作和实际经验的问题;
2, 面试中需要有人充当黑脸和不讲理的人, 就是要pressure一下面试者, 看他的心理
素质和沟通能力, 这种面试后一般都要跟candidate说明一下, 道个歉的. :-)
另外, 一些你所谓的***学院派***的问题, 根本就不是靠记忆的, 死记硬背你也记不住
, 东西太多了
没troubleshooting过protocol over MTU的问题的人, 会记得住几层mpls label的
packet size?! 那东西也许你死记硬背可以记得住, 我是记不住的. | n**********l
发帖数: 271 | 6 There is a discussion on NANOG about interview questions, thought it's
interesting
http://www.mail-archive.com/n***[email protected]/msg50903.html
I read all those replies and felt I didn't know a thing about networking...
Any thought on how far networkers need to go on "how things work"?
(yeah as far as one can, but consider contraints...)
For example, T1 signaling, link layer...
I have similar experience on memorizting stuff.... IMO TShooting is the best
way to learn and remember things... |
