What are the skills required for KPO jobs as distinct from BPO jobs?

KPO includes those activities that require greater skill, knowledge, education and expertise to handle than a typical BPO job. For example, An insurance company might outsource data entry of its claims forms as part of a BPO initiative, it may also choose to use a KPO service provider to evaluate new insurance applications based on a set of criteria or business rules; this work would require the efforts of a more knowledgeable set of workers than the data entry would and hence domain/industry skills are desired.
What are the types of assessments used?
In the KPO space, domain-based assessments can be customized to count for the complexity of a job role or project and select eligible candidates. These are coupled with general abilities tests like analytical, attention to detail; communication skills like written English ability; and functional skills like typing to arrive at and select the best talent.
