Probably one of the worst interviews I've done in a while. Although they got back to me fairly quickly, I felt through the entire interview that they weren't interested. It was best if they had refused me from the beginning.
I applied for a senior position, sent out my resumé and got a response that "the position wasn't the best for me" and offered if I wanted to apply to a different non-senior Software Engineer position, even though my experience ranges for over 7 years. I accepted nonetheless and took it as a challenge to prove my worth. No phone call, no way for me to introduce myself, just straight ahead to an online coding challenge. I got the challenge and only had 1hr 15min to code 5 different challenges, all ranging from easy to medium difficulty.
Even though I had the solution in mind for every challenge, 1hr was NOT enough time to complete it all. I felt as the recruiter almost set it the challenge up for failure on purpose. Writing the implementation for each one with good coding standards, testing for every scenario mentioned PLUS all the hidden scenarios is not something one can do with in a such short amount of time. I've interviewed at other and bigger companies with tougher interviewing processes and I was given at least 2hr30min to complete two questions... Now imagine 5!
After my follow up with the recruiter explaining that I'd be more than willing to complete all the remaining challenges, I just got a response with "you can apply again in 6 months".
In short, I do not recommend it. Don't waste your time here, they are not willing to hear your story.
