Hours after applying I received an email expressing the company's interest in interviewing me for the post. A few emails later a zoom interview was arranged for the next morning. I spoke to a lady via video call. She briefed me on what the company does, my daily tasks etc. She asked me about my past experience and to tell her about myself. It was very light hearted and relaxed. 10 minutes later it ended and I received an email congratulating me on passing the first round and organising the next interview with the boss- which was set for that same afternoon. Again on zoom but this time far more serious. More questions specific to my skills and level of compatibility; so you have to know what they are looking for.
