I am using same format of .bib file entry, but get different output formats in beamer. Here is the MWE:

documentclass{beamer}



usepackage[english]{babel}

usepackage[utf8]{inputenc}

usepackage{lmodern}



%% Bibliography

usepackage[backend=biber,style=alphabetic,citestyle=authoryear]{biblatex}

bibliography{bibfile.bib}



begin{document}



begin{frame}{Trial frame}

cite{Borzacchiello2017} \

cite{LEGUENNEC2018} \

cite{Goldfarb2014} \

end{frame}



begin{frame}[allowframebreaks]{References}

    printbibliography

end{frame}



end{document}

with the following .bib file entries:

@article{LEGUENNEC2018,

    author = "Le Guennec, Yves 

         and Brunet, Jean-Patrick 

         and Daim, Fatima Zohra 

         and Chau, Ming 

         and Tourbier, Yves",

    title = "A parametric and non-intrusive reduced order model of car crash simulation",

    journal = "Computer Methods in Applied Mechanics and Engineering",

    year = "2018",

}



@Article{Borzacchiello2017,

    author="Borzacchiello, Domenico

        and Aguado, Jos{'e} V.

        and Chinesta, Francisco",

    title="Non-intrusive Sparse Subspace Learning for Parametrized Problems",

    journal="Archives of Computational Methods in Engineering",

    year = "2017",

}



@article{Goldfarb2014,

    author = "Goldfarb, Donald and Qin, Zhiwei",

    title = "Robust Low-Rank Tensor Recovery: Models and Algorithms",

    journal = "SIAM Journal on Matrix Analysis and Applications",

    year = "2014",

}

But I get the following output. As you can see the format is different in reference slide and citation as well:

I would like to have:

1) citation format : "FirstAuthor Year", preferably without "et. al"

2) Reference slide format: names of all authors, with first names abbreviated

To control the namelists according to your specifications, biblatex's package options are enough. maxcitenames=1 will give citations with only the first author (regularly, with "et al."); maxbibnames=99 should be enough for normal cases to include all authors in the bibliography; giveninits=true will abbreviate given names throughout.

To remove the "et al." of shortened authors lists a not very elegant, but simple solution, is to redefine the corresponding localization string with:

DefineBibliographyStrings{english}{andothers={}}

I wouldn't do that though. The "et al." is there for a purpose.

Note I have changed your style=alphabetic,citestyle=authoryear to style=authoryear. Mixing those styles, though technically "works", is bound to give you some inconsistencies or sub optimal results.

documentclass{beamer}



usepackage[english]{babel}

usepackage[utf8]{inputenc}

usepackage{lmodern}



%% Bibliography

usepackage[style=authoryear, maxcitenames=1, maxbibnames=99, giveninits=true]{biblatex}

bibliography{bibfile.bib}



% Not elegant, but simple enough for the purpose

% Still, it is not recommended, as it breaks the relation of citation and

% reference in the style.

DefineBibliographyStrings{english}{andothers={}}



begin{document}



begin{frame}{Trial frame}

cite{Borzacchiello2017} \

cite{LEGUENNEC2018} \

cite{Goldfarb2014} \

end{frame}



begin{frame}[allowframebreaks]{References}

    printbibliography

end{frame}



end{document}

Resulting in citations:
