welcome to the mind fuck.
you're in it now. smile. study. don't have fun at training. don't overeat, oversleep, talk too much, listen not enough, don't do anything that may draw attention to you. Where dark suits, never browns, greens. Do wear cufflinks, have a snazzy watch, drive a car you will have to defend at some point with a customer. Do study hard, don't say it is easy. Do act like every interaction you have with anyone not at your level is an interview. Do treat each activity as you will be judged for your entire career at ISI. Don't disagree. Do vomit up all the sales jargon you have role played when you are in the field with mgmt. DO spend more time sharing good stories that you have created with customers to show the "group" that you are making a difference than what is really occurring in the field. Do apologize to your spouse for missing that. Do apologize for family and friends for not attending that>>>> bc you cant take vacation in the last month of a quarter, or around a national meeting, or if you are not trending well in your number. DO live in 90 life cycles. Don't think you have a job in 91 days. Don't trust anyone. Don't believe it when management asks for feedback. Do believe you may make good money. Don't believe it will be anywhere near what it used to be. Do know your manager will make or break you so it is the luck of the draw. Do know that promotions come from a combo of luck and mindless ass kissing. Do know that you will be sold down the river the moment your direct report is in jeopardy. DO know that the only HONORABLE people in the org are in engineering and RD. Do know that the product is very reliable and the only reason the company is as amazing as it is.
Do know that a life can be had in Med device w/o ISI where you can make great money and balance it all in the process.
