I applied to a large and very well known global organization through an online application, and someone from their team contacted me mid-March wanting to set up a telephonic interview on March 27th. Below is a short history of events that has taken place thus far. Even though the role is a mid-managerial-level one, my reporting would be to a senior manager in another country and hence, they don't have a specific department in-country for this position yet. I'm confused by the whole ordeal and as mentioned, the organization is quite large / well-known but the experience has overall left me confused. Am I just thinking too much? - March 27th - initial phone call (one hour) with the Senior Manager who reached out to me - Apr 02 - asked to complete an online test (2 hours) along with preparing a PPT based on a case study given to me to review and analyze - April 06 / 08 - completed the online assessment test and submitted my presentation - Apr 12 - got an email mentioning I had another interview scheduled with the Senior Manager's direct reportee, ie: the Manager who works with him - scheduled for Apr 15 - April 17 - got an email I was shortlisted for the final round, based on my online test, powerpoint presentation, and conversation with the Junior / Senior managers on call. Invited for an in-person interview with the Senior Manager i have been on calls with, along with two VPs in-country on April 23rd - April 23rd - in-person interview goes reasonably well - expected to head back from then within 10 days - April 24th - mentioned on email they would take one more week to make a decision. Mentioned someone would contact me for a "final" phone interview with the Regional Director on May 2nd. Was asked in the meantime to share my references contact details (2 of them) which I did. - May 2nd - had an extremely positive conversation with the Regional Director (or so what I thought) who said towards the end of the call they should be getting back to me within a week. - May 3rd - this is around the same time I came to know both of my referred contacts (reference checks) completed the form which was sent to them for my review. - May 8th - didn't hear back from anyone - sent an email to the Senior Manager asking for an update. Got a reply quickly, telling me I was in the race with one other candidate and they expect to make a final decision within one week. - Today - May 14th - one week ends today... Confused on if I should follow up again with a polite reminder, or let things play out on their own...? TLDR: Application process started March 27th - four calls, an online test, a case study, an in-person interview and a reference check later, still no offer or decision. Confused whether to follow up or stay quiet for a bit more time.
