Motorola Solutions Perl/Systems Developer interview questions

Had interview with three people, it was a technical panel meeting. Questions based only by things that I had in my resume even though position that I was applying for was about perl and linux/sunos skills. Also I learnt that I am not applying for a job that is described on their website, but I will be assigned to one of the teams and I will do tasks within this team. Questions: - write regexp in perl that will match certain part of the string - difference between having / where clause (sql) - what is the ttl (network) - how to deal with routing loops - virtualization (vmware) - about my master thesis Interview done in Polish. They just checked my english by asking me what am I doing in free time.
