Help Scout Software Engineer interview questions

Going through the resume. The interviewer is pretty rude and condescending. Asks if you have any questions, but then immediately responds with "it's in the ad description" or "we have a blog post about that". Doesn't seem to be a great work culture. Also, they mentioned they would move to the next step in the interview process and never did. Very unprofessional.

I applied online. Was later interviewed on appear.in. First round was 2 short interviews with a team leader and a developer. The team leader was nice and friendly. Asked mostly general questions about my background and qualifications. The developer asked me general simple screening questions about databases, Object Oriented design and Solr/Elastic Search. Next had an interview with someone from the HR. Again simple questions about the salary and joining date. Was told that a project will be sent that I have to work on. The project was actually bigger than what they described. They said it should take a day or two; however, the requirements were actually somewhat vague. They assumed that I already had experience in Solr or Elastic Search. I completed the project and received a general email saying that my work doesn't align with their design and testing goals. They did mention some general negatives and positives in the mail, but they didn't discuss anything with me. Due to the vague nature of the requirements I had to assume a lot and didn't pay much attention to the end resulting code which seems was their main goal. My advice is to deliver clean code with clean unit tests. Don't over abstract nor chose certain design decisions that has to be explained in person. Go for a simple clean design that satisfies the requirements. One thing that caught my attention is that the developer kept over repeating that reviews for the project will be anonymous. I also noticed that no Asians nationalities were mentioned in the development teams favoring eastern Europeans countries.
