My apologies, if I have offended or hurt you in any manner. You are correct, there are smart and genuinely nice people in Qualcomm and hence I mentioned, I would be weary of and not downright reject an ex-Qualcommer. But there is a toxic work culture in a lot of teams and people, who have worked at Qualcomm long enough, could potentially carry it over. The smart and nice folks at Qualcomm, in my experience, tend to be more of an exception than a rule.
The 2 year comment can be broken down into, 1 year to figure out Qualcomm and all the teams + the other 1 year to search newer opportunities. Considering the tech scene at SD, it takes longer for folks to find jobs elsewhere.
