How long after the HR call did you receive the email for booking an interview? I had a call early this morning and still haven't received the email, worried they might have forgotten.
I went on the online portal to have a look anyway and found that I could book a slot through the Telephone Interview button. Is that how you did yours? Also, do you have to click the big Submit Application button after you've booked a slot?
Depends on if you're lucky/submitted early. Right now you might have to wait anywhere between a few hours & a days after submitting your application, just to get to the online tests stage. You'll have 3 days from the time you receive the email to complete them.
Once you're done, you could be waiting for a few days or a few weeks to get your feedback report and find out if you've passed. It's likely that you won't get both at the same time. I got told whether I got through almost 2 weeks after I completed the tests, then got the feedback like 4 days after that.
If you've passed, you'll then have to wait for a member of HR to contact you by phone to explain the interview process and how to book a slot. This could take about a week.
Apparently, you'll find out if you've been successful one working day after the interview. Don't be surprised if you have to wait a few days, though; they probably have 100s of candidates to get through. If you've passed they'll call; if you've been rejected, they'll email.
If you submit now, you're likely to have to wait longer to hear back from them after the first stages. But, you might get lucky, so fingers crossed!
