Harmonia Senior Software Developer interview questions

Applied online via their website. I was contacted within 24 hours for a quick technical screening interview, scheduled in-person interview for two days later. Second interview was deep technical with a technical manager and a technical peer. Questions were challenging. Passed. Third interview was in a day, with Program Manager. Told would revert after checking references. Got a call from COO for a quick 5 minute "culture-fit" call, offer made later that day. Total process was very quick.
