In technical level-1,tell me abt yourself.OOPS concepts were asked.Be thorough with OOPS concepts. And four programs were asked. 1.given input:5 print the following pattern: 1 2 3 4 5 6 10 11 15 16 20 21 22 23 24 25 i tried to code.Almost got it.But he asked me a more simpler way.And helped me to do it simpler.the interviewer was very friendly. 2.given input:10 print: 2143658107 hint:for i=even,cout<<i-1; for i=odd,cout<<i+1; i told him using arrays in the same approach but slightly different.he asked me without using arrays.he asked me to keep start index as 1,then i was able to get the logic. 3.input:5 print: a b b c c c d d d d e e e e e 4.input:1,2,3,4,5,6.............100 output:2,1,4,3,6,5.................99 the interviewer just saw how quickly i was able to get the logic.so dont panic if you dont do it efficiently.just try to get the logic. the other programs which my friends got are- 1.check palindrome 2.print alphabet a 5 times without any loop. 3.print pyramid pattern. 4.sub palindrome within a palindrome. 5.count number of vowels. 6.find number is odd or even without using modulo(hint: use bitwise operator& with 1). 7.number of words in a sentence.and print the longest word. i was not asked attend to tech level-2.so was directly asked to attend hr round.few of my friends were asked to attend tech-2.hr was very friendly.she asked abt my family,my non technical skills,told abt 2 yrs bond etc. Be thorough with c concepts and oops concepts and be strong in coding.what aspire systems expects is good coding skills and communication skills. I wish you to become a future ASPIRIAN. If offered,they would send off you with a cool aspire t-shirt and an offer letter. ALL THE BEST.
