SLK Group Senior Engineer - Testing interview questions

It was a Referral Walk-IN on AUG 7th 2018 :- 1) 2 Technical Rounds and 1 HR Round About their Process:- 1) I was called for Technical round 1 and it went good and soon after I took my seat I was called for Technical round 2. 2) I was asked to wait after I finished my 2nd Technical round at 12 pm. 3) HR's asked us to go for lunch after we all (candidates) waited for HR Round. 4) I had asked the HR to check whether I had made through the 2nd Technical round so that I can leave for the day If I hadnt cleared it at 1 PM 5) We all came back from lunch at 2pm and waited for another 1 hour till 3pm to get the confirmation as to whether I was IN for the 3rd round. Still no reply from the HR. 6) At 3:30 PM I again asked the HR for my status with respect to 2nd Technical round. And she replied me to wait and she will check and let me know about it. 7) At 4:30 finally they told me that I can leave for the day . Such a hopeless and irritating experience at SLK at their Referral drive. Making a candidate to wait for 4.5 hours and later they end up telling that we can leave for the day. Totally inappropriate and this is not appreciable. People at SLK have to learn the ethics first before they conduct such walk-in drives. I am not at all sad or worried that I did not make through as there are several other companies outside in the IT World. But making a candidate who has applied leave from his current organization and given his dedicated time for SLK walk-in drive making to wait for 4.5 hours without letting him know the results is totally disgusting. This is not a professional manner of taking interviews or conducting Walk-ins. PLEASE DO NOT ATTEND SUCH WALK_INs at SLK . Because they dont value your time. Unprofessional and disgusting experience. Totally BAD. !!!
