LexisNexis Legal & Professional Software Engineer-II interview questions

The process took 3 months from time of application to the final decision. I applied online in October via LinkedIn jobs and got a call from the recruiter. Had a general discussion with recruiter followed by a technical phone round (no coding) with a team lead. The phone interview was entirely on technologies mentioned in my resume. Later was invited for an onsite interview consisting of one on one 5 rounds (45 min each) with Sr Director, 2 Software Engineers, project manager, and data scientist. All the interviewers were very friendly. The five rounds were: 1. Resume discussion and product design question. 2. General technical discussion round. 3. White board coding (leetcode easy) and writing custom hash function and HashMap internal implementation. 4. Behavioral round 5. General discussion and the company product demo. I followed up with my recruiter with no response from his side for a month. They took more than a month to let me know the decision that I was not being offered the job.
