Lockheed Martin interview questions

Had an initial phone interview assessment, followed by a second technical interview online. The process was followed by a job offer and a contract was signed. Whilst waiting for my Security Clearance from the UK home office, the job offer was rescinded and given to another candidate. This was a challenging scenario on my part as I was never told this could happen and had turned down interviews and offers of employment elsewhere.

Video interview. Questions on software engineering concepts such as data and algorithms. Very casual process. There wasn't any hard questions that are out of the ball park. Interviewers were nice and accomodating
