Just got this e-mail last night from Shell,

Thank you for your application and for the interest you have shown in Shell.
In view of Shell's Joint Venture partnership and/or licence agreements with your current employer, we regret to advise you that we are unable to accept your applications to positions in the Shell group of companies.
If you leave your current company and then wish to apply to Shell, we will be pleased to review any future application(s) you may make.
If you are currently employed by a Joint Venture company where Shell is the operator, it may be possible to transfer to Shell staff status after a minimum service period of 2 years. Any opportunity would be based on Shell's business need considerations and your performance. If you wish to be considered, you should contact the Skillpool Manager or Capability Advisor in your region, or a local HR Advisor.
Kind regards,
Shell
