Jobs for physics PhD's / At what point can you claim to "know C++"? I am a year away from graduating my HEP PhD and I'm thinking about what comes next. Postdoc is an obvious option, but the impression I get from this site and elsewhere is that it's a short-sighted one. I'm therefore thinking about what else I can do, what I've got to offer in other fields/careers. My PhD has almost solely involved working with C++, but whilst I am no rookie at this point, I am by no means an expert either. I had sat one C++ based module as an undergrad but by the time I started my PhD, almost all had been forgotten and I was essentially learning it from scratch. Furthermore, my PhD has been about doing what I need to with C++ to get physics results, not about getting a broad knowledge of the language for its own sake. I'm comfortable with the basic machinery of it - well-versed in terms in terms of the syntax, the use of loops, arrays, functions, structures, vectors, I can de-bug what I write, but I know there must be so much more to it that I am unfamiliar with. For example, despite understanding what a pointer is since they appear in all the "beginners" literature, I have never used one in any practical application. Or say I was asked in an interview the meaning/use of "istringstream" or to explain "inheritance", I would be unable to. What I'm hoping for here is for someone to sum up what you would expect an applicant for a C++ based job* to know. OR, can I apply for C++ -based jobs assuming employers will take me on assuming that I can pick up what I need as I go along? I'm also considering starting to learn another language in my spare time, but I do not know which one and welcome any suggestions. Thanks. * a job that a HEP physics graduate might typically apply for, eg. quantitative analyst has crossed my mind.
