Got an e-mail from HR saying they want to schedule a phone interview and they need my contacts. The initial phone interview was about 30 mins. They asked about previous work history, told me about the interview process and said they will contact me again if they are interested. A week later, they contacted me to set up a technical interview with a Sr. Acoustics Engineer. The interview was not very well structured, it was more of a conversation, but at a technical level. Talked about frequency response of mobile devices, IIR FIR filtering, past experiences. This interview took about an hour. I was told I would be contacted again by the HR for the next steps. However I did not get contacted? I followed up and eventually got through, they said an offer was already made but, if it is rejected I will be next.
