Sibros interview questions

first interview went well (15 minute talk with hiring team). they told me im going to have 3 other interviews, 1 with senior software and 2 for coding. the interview with senior software was the coding interview and i wasnt prepared because i thought its a regular interview. i solved the problem but because we talked a lot i didnt have time to finish the answer and got rejected. i told them this but they didnt give me another interview
