Phone screen setup by HR who was very nice and professional. First phone interview was with Team lead. Again, very nice and professional but extremely difficult interview for a first screen. Deep dove right into linux, multicast, python, and trading terms. At the first sign of stumbling he basically said, thanks but no thanks (in a respectful way). Their bar is HIGH. Expect a grilling.

test on HackerRank, basic question, with SQL Fix puzzle,python,linux then call on zoom. tell about work, given some situations, how do you handle?how do you lead? some back order flow questions. then test puzzle, python, linux,again
