(Email Screening Question) The following areas map to technologies we use on a regular basis at GitHub. Experience in all of these areas is not a prerequisite for working here. We'd like to know how many of these overlap with your skill set so that we can tailor our interview questions if we move forward in the process. Please assess your experience in the following areas on a 1-5 scale, where (1) is "no knowledge or experience" and (5) is "extensive professional experience". If you're not sure, feel free to leave it blank. Just place the number next to the corresponding areas listed here: • coding o comp-sci fundamentals (data structures, big-O notation) o C or C++ programming o Go programming o git usage o git internals o shell scripting o ruby programming • troubleshooting o debuggers (gdb, lldb) o profilers (perf, oprofile, perftools, strace) o network flow (tcpdump, pcap) • large system design o unix processes and threads o sockets o signals o mysql o redis o distributed systems • operational experience o reading and debugging code you’ve never seen before o helping other engineers understand and navigate production systems o handling large scale production incidents (external communications, internal coordination)
