Interview
Be prepared to dust off college books and try to remember every algorithms/codes that your learned in the past years. Phone interview is a hit/miss on one technical question.

It is difficult for those who have worked on a specific field for a long time unless they have plenty of time to review.

Interview
there are phone interviews and on site interviews.
for on site, they paid for plane, hotel and food expenses. the recruitier and five skilled software engineers interviewed me each a time, asking software design and development questions. that was a tiresome but very fun and enriching experience
