I got the interview call through a recruitment firm . Job would be under Siemens pay role. Project Engineer is the profile name.I was dealing with PLC and SCADA developent but the Siemens was expecting guys with Project engineering background (Panel engineering,IO list creation,Instrumentation knowledge...) .I never done those stuffs . I had knowledge about Schneider PLC and SCADA's . So questions were asked about Siemens systems. PLC and SCADA related question answered almost. But when it comes to instrumentation I was pretty weak in that area. Interview questions were pretty straight, only giving importance to basic stuffs rather than going in depth .
