Thoughts on leaving cisco

I have recently left Cisco. This post is a rant on how i feel while leaving I worked at CCBU. A department which is filled with incompetent dev and even more incompetent managers. Not surprisingly all employee were Wipro contractors who became full time due to sheer amount of time spent. Managers expect you to lick their ass to get promoted. Since i am non ass licker employee, i was never in his good books. While resigning my manager threatened that he will extend my notice period and gave me tasks to finish off if I "ever" wanted to leave I feel very happy leaving such shitty place. I wish never to return here again. At my tenure my growth has been negative, and I became lazy. Now trying to get out of this lazy zone in my next company Ps- I know there are good parts of Cisco as well. I just happened to be in the wrong part. This post is me venting out about my experiences. This is just personal opinion
