Smartfrog&Canary interview questions

Went through a few phone interviews - the original with a manager in recruiting, who was very kind and easy going. The second was with the head of staff, she had the opposite personality. Not very easy to read, but overall an OK experience. I thought it went well, but in the end they ghosted me, which I find pretty unprofessional, especially after a series of interviews...

I applied online for the Tier 3 Technical Support engineer position. The job recruiter at Canary reached out to me to setup a first round interview with me. The first round interview with me went fine so she placed me into the second round interview with the manager. My second round interview with the manager went fine in my mind. But, the day after they determined they didn’t want to pursue me.
