SICPA Software Developer interview questions

Interview is normal technical interview, go thru home assignment together. Need to explain certain things and answer a few question based on the code submitted. Have pseudocode test at the last of question. Give the solution and explain while doing the test. Interviewer so nice and well explain on everything. But be careful with the HR, i dont know why like to ghost the candidate. Not really friendly. I pass everything but yeah at the end, offer letter not issued because other candidate suit them more. I have positive experience with the interview process but not with the HR
