I applied to Sensi.ai via ukrainian recruiters several times, even had a bunch of HR calls with them, but apparently my resume was never forwarded to the client as I heard no response from them. I remember this firm particularly because I was approached with this name several times, all of which resulted in my wasted time on 40-minute recruiter calls, without any further feedback. I would not recommend applying via ukrainian recruiters because you will never get presented to the client.
