Commitment to Privacy
encrypted
Your resume, transcripts, and all uploads are encrypted from the moment they enter our system. It is never reused, never shared, and never modeled. Ever. Everything is kept confidential only between you and your designated expert.
anonymize
We will never ask for your real name, school, or workplace unless required by the service. You can use a nickname, a temporary email address or remain completely anonymous and our support and quality will not be compromised.
removals
At the end of the project, your data will also disappear. You can request deletion at any time, and we will permanently delete your files, messages and history within 48 hours, without exception.
OA Frequently Asked Questions
Is it possible for a system to detect an OA proxy
We use remote tools like Todesk to carry out our work, ensuring the process is completely undetectable. With over a thousand successful sessions in the last 8 years and a perfect success rate, you can be confident that your desktop and browser won't be monitored.
What is the success rate of the OA online proxy interview?
Up to now, the success rate of our OA generation service is 100% whether it is for large factories, small and medium-sized factories, or Startup and other enterprises. Our generation teachers are all from North America and the UK Top 20 universities, and they all have the experience of working in large factories in important technical positions, plus they are familiar with the interview questions of OA round interviews of various companies, so they can easily manage the OA generation interviews.
Is there a time zone problem with OA generation?
OAassit currently has three teams in the US, UK and Australia, and has the flexibility to match candidates with substitute teachers in the same time zone.
