Phone screening. After received an outreach letter via LinkedIn and waiting a very lengthy waiting period, I finally went through two phone interviews. The first was great, but the second was incredibly unprofessional, in that it was conducted on a speaker phone via which I could barely hear the interviewers questions. I brought this up at the beginning, and she simply asked me "is this going to be a problem?". Under the circumstances I felt pressured to acquiesce, however the conditions surely made for a sub-par interaction and representation of myself, as I was constantly straining and under extra pressure to simply hear what the interviewer was asking. The questions were very (purposefully) technical and complicated.
At the end of this extremely drawn out experience, I simply got a late email with a one-sentence text along the lines of: 'Sorry we've decide to go elsewhere'.
