Hii,If you are looking for campus recruitments like they do in engineering stream then my friend you are in for a disappointment.

Architecture has no recruitments, no job placements.

If you have a good portfolio then you can apply for any office. Although you could get into a good office during your internship period(because of contacts, either of your professors or seniors or yours). You can continue there after graduating.

Regarding payscale it varies, a senior of mine applied for a firm in Singapore and they were willing to pay him 15 LPA. While one of my friend is stuck at a local firm who are paying him 8000 per month. It all comes down to your portfolio and contacts. If you are worthy you will sustain this field.

Hope this answers your question.
