Overall BrightHire has a really nice UI and is very simple to use. It is also quite fast. It appears as "Notetaker" for your company during the interview. However I am unsure of its capabilities (at this time) to very accurately capture transcripts in languages that are not English (it could be but I cannot attest to it right now). Its ability to capture technical jargon is not perfect. I would recommend using BrightHire when you you are conducting non technical interviews at this time
Spark Hire is well suited for the growing organization which hiring managers are always on the move. The chance of physically having an interview is less and even candidate sorting & tracking is tough. In this situation, Spark Hire is the best fit. In addition to this, when you need someone very special for a role this application will come to your help. It will ensure the best candidate is recruited as it will go under the multi layer assessment.
Spark Hire is easy to use for both us and the candidate/interviewee. There is not a huge learning curve to being able to implement the program. Additionally, our clients (who are given access to the interviews) don't find it difficult to use, and our candidates have very few problems when recording their video interviews
I have not used the support that much with Spark Hire but it seems that there are a lot of features available for support and different resources that are provided on Spark Hire's website. For the most part, the system is very user-friendly and it's easy to navigate and figure out things on your own.
I can't remember the names of the other companies I reviewed but I chose Spark Hire because I could purchase the service on a monthly basis. This is an important feature for us since we're a small business.
