National Circuit Assembly interview questions

Can you Solder? What is previous experience? Do you have production work experience in soldering? How would you repair? Do you have to have a schematic or can you repair based off of a known functional problem with the unit and a part list know to fix this functional problem? (i like to call this repairing by brail. your not sure what was broken but just replace these compontents. no going around a loop or going through a node in circuit diagram.( a sub system with electrical input and electrical outputs.))
