As a PhD qualified expert I found this job really challenging. Every job has some expectations from their new entries, and for getting into the services which are best in the field, you need to meet some extra conditions as well. Similarly, for a job as a research helper, there are certain conditions that you need to meet before applying for the job. First of all, you need to be qualified, and especially for research paper help, you should have completed at least a master's degree in any field.
