Interview Preparation Tips
Interview preparation tips for other job seekers - Basically they are playing, I was accepted in all rounds, and the last meeting I should get an offer,
and they told me to wait 1 or 2days max and they kept me hanging for a week and half and I was sending them emails, LinkedIn messages, but no reply and when they replied after a week and smth they were like wait one more day we are almost to finalise the offer and in the main time I rejected other offers I thought they were serious and they give me a good offer on phone not on papers, then after 2weeks they send me a general linkedIn answer that I wasn’t accepted and they move forward, I was like after keeping me 1month and you said you are gonna sign the contract in a few days then u send me a general answer :((
