Adi has application response time and final interview response time mixed up.
In terms of physically applying, you should expect to hear back as early as a week after your application, or as late as several months.
It really just depends on demand, supply, and whether you've been referred.
Given that you've "cold applied" I would both expect a lengthy wait and lower odds of being invited to interview. In the future, I highly recommend you try to network before applying!
That said, given it has been 1.5 months already, you should feel free to reach out (politely) to HR asking if they happen to have an update.
Fingers crossed for you!
