What's the weather like there these days? I ask because I think #6, 7, + 8 together might make a really nice outfit, and if you want something a bit lighter/brighter, try top # 4 with the pants in #7, and the jacket in #8.
You can easily punch it all up with colourful accessories - I keep thinking of CocoLion's neon yellow/lime skinny belt or something along those lines.
I also think the blouse shown in photo #2 is really nice, and you could pair that with grey Modern Boot pants from GAP, and the jacket in #8 if the style of blouse isn't too fussy with the pattern in the jacket.
Just for the record, I don't think the snakeskin patterned jacket is too 'out there' at all, because as you said, it's a simple style with clean lines - the only detail is in the pattern, and I actually think this is what makes the jacket a lot more interesting.
I think if you get the snakeskin jacket and the Modern bootcut pants in grey - you'll be able to come up with a nice interview outfit - in fact, I'm willing to bet that these two pieces will go a long way in your wardrobe. Are you ordering the snakeskin jacket online and can't try it on? It all depends on how the jacket fits. Also, can the jacket be returned if need be, without a lot of hassle? In case it doesn't fit right, or the colour's not quite what you wanted or what have you?
