Dearest Prabha,
Has he looked at any job sites like jobsuk etc ?
What is his domain like media , banking ? It would be better to look out for jobs in his domain with his expertise.
There are several job sites that display adverts related to a specific domain and accordingly it would be easier for him to focus and decide on the job opportunities.
The job market has picked up slightly since past month.
The other means of looking out for a job is referral program where exisiting employees can refer the candidate for interview.UK job market is very open to referral program.
Is he looking for only permanent jobs or open to contracting as well ?
Probably you might be already aware that contracting in UK is different to contracting in US and is more lucrative if you want to spend few years in UK and go back to homeland.
All the best.
P.S: I loved your yoga pdfs.Great stuff !
