Lenovo Hyperscale Development Manager interview questions

Was painful. Recruiter called me up and explained the job role and said, I was match. Went trhough salary expectations and everything, but I never received a follow up call or an email. I emailed like 5 times before giving up. Its a common courtesy to reply to emails. I understand that, I might not be the exact match. but I expect a response. highly unprofessional attitude
